    Changelog:

     - Fix: 69932: Fix request end access log pattern regression, which would log      the start time of the request instead. (remm)      + Fix: 69623: Additional fix for the long standing regression that meant      that calls to ClassLoader.getResource().getContent() failed when made from      within a web application with resource caching enabled if the target      resource was packaged in a JAR file. (markt)      + Fix: Pull request #923: Avoid adding multiple CSRF tokens to a URL in the      CsrfPreventionFilter. (schultz)      + Fix: 69918: Ensure request parameters are correctly parsed for HTTP/2      requests when the content-length header is not set. (dsoumis)      + Update: Enable minimum and recommended Tomcat Native versions to be set      separately for Tomcat Native 1.x and 2.x. Update the minimum and      recommended versions for Tomcat Native 1.x to 1.3.4. Update the minimum      and recommended versions for Tomcat Native 2.x to 2.0.12. (markt)      + Add: Add a new ssoReauthenticationMode to the Tomcat provided      Authenticators that provides a per Authenticator override of the SSO Valve      requireReauthentication attribute. (markt)      + Fix: Ensure URL encoding errors in the Rewrite Valve trigger an exception      rather than silently using a replacement character. (markt)      + Fix: 69871: Increase log level to INFO for missing configuration for the      rewrite valve. (remm)      + Fix: Add log warnings for additional Host appBase suspicious values.

Pull request #902 by Brian Matzon. (markt)      + Fix: Change the SSO reauthentication behaviour for SPNEGO authentication      so that a normal SPNEGO authentication is performed if the SSL Valve is      configured with reauthentication enabled. This is so that the delegated      credentials will be available to the web application. (markt)      + Fix: When generating the class path in the Loader, re-order the check on      individual class path components to avoid a potential      NullPointerException.

(remm)      + Fix: Relax the JSSE vs OpenSSL configuration style checks on SSLHostConfig      to reflect the existing implementation that allows one configuration style      to be used for the trust attributes and a different style for all the      other attributes. (markt)      + Fix: Better warning message when OpenSSLConf configuration elements are      used with a JSSE TLS implementation. (markt)      + Fix: When using OpenSSL via FFM, don't log a warning about missing CA      certificates unless CA certificates were configured and the configuration      failed. (markt)      + Add: For configuration consistency between OpenSSL and JSSE TLS      implementations, TLSv1.3 cipher suites included in the ciphers attribute      of an SSLHostConfig are now always ignored (previously they would be      ignored with OpenSSL implementations and used with JSSE implementations)      and a warning is logged that the cipher suite has been ignored. (markt)      + Add: Add the ciphersuite attribute to SSLHostConfig to configure the      TLSv1.3 cipher suites. (markt)      + Add: Add OCSP support to JSSE based TLS connectors and make the use of      OCSP configurable per connector for both JSSE and OpenSSL based TLS      implementations. Align the checks performed by OpenSSL with those      performed by JSSE. (markt)      + Add: Add support for soft failure of OCSP checks with soft failure support      disabled by default.

(markt)      + Fix: HTTP/0.9 only allows GET as the HTTP method. (remm)      + Add: Add strictSni attribute on the Connector to allow matching the      SSLHostConfig configuration associated with the SNI host name to the      SSLHostConfig configuration matched from the HTTP protocol host name. Non      matching configurations will cause the request to be rejected. The      attribute default value is true, enabling the matching. (remm)      + Fix: Graceful failure for OCSP on BoringSSL in the FFM code. (remm)      + Fix: 69866: Fix a memory leak when using a trust store with the OpenSSL      provider.

Tenable has extracted the preceding description block directly from the SUSE security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The version of Tomcat installed on the remote host is prior to 10.1.52. It is, therefore, affected by a vulnerability as referenced in the fixed_in_apache_tomcat_10.1.52_security-10 advisory.

  - Improper Input Validation vulnerability in Apache Tomcat Native, Apache Tomcat. When using an OCSP     responder, Tomcat Native (and Tomcat's FFM port of the Tomcat Native code) did not complete verification     or freshness checks on the OCSP response which could allow certificate revocation to be bypassed. This     issue affects Apache Tomcat Native: from 1.3.0 through 1.3.4, from 2.0.0 through 2.0.11; Apache Tomcat:
    from 11.0.0-M1 through 11.0.17, from 10.1.0-M7 through 10.1.51, from 9.0.83 through 9.0.114. The following     versions were EOL at the time the CVE was created but are known to be affected: from 1.1.23 through     1.1.34, from 1.2.0 through 1.2.39. Older EOL versions are not affected. Apache Tomcat Native users are     recommended to upgrade to versions 1.3.5 or later or 2.0.12 or later, which fix the issue. Apache Tomcat     users are recommended to upgrade to versions 11.0.18 or later, 10.1.52 or later or 9.0.115 or later which     fix the issue. (CVE-2026-24734)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - Improper Input Validation vulnerability in Apache Tomcat Native, Apache Tomcat. When using an OCSP     responder, Tomcat Native (and Tomcat's FFM port of the Tomcat Native code) did not complete verification     or freshness checks on the OCSP response which could allow certificate revocation to be bypassed. This     issue affects Apache Tomcat Native: from 1.3.0 through 1.3.4, from 2.0.0 through 2.0.11; Apache Tomcat:
    from 11.0.0-M1 through 11.0.17, from 10.1.0-M7 through 10.1.51, from 9.0.83 through 9.0.114. The following     versions were EOL at the time the CVE was created but are known to be affected: from 1.1.23 through     1.1.34, from 1.2.0 through 1.2.39. Older EOL versions are not affected. Apache Tomcat Native users are     recommended to upgrade to versions 1.3.5 or later or 2.0.12 or later, which fix the issue. Apache Tomcat     users are recommended to upgrade to versions 11.0.18 or later, 10.1.52 or later or 9.0.115 or later which     fix the issue. (CVE-2026-24734)

Note that Nessus relies on the presence of the package as reported by the vendor.

The version of AOS installed on the remote host is prior to 7.3.1.7. It is, therefore, affected by multiple vulnerabilities as referenced in the NXSA-AOS-7.3.1.7 advisory.

  - LIBPNG is a reference library for use in applications that read, create, and manipulate PNG (Portable     Network Graphics) raster image files. Prior to 1.6.55, an out-of-bounds read vulnerability exists in the     png_set_quantize() API function. When the function is called with no histogram and the number of colors in     the palette is more than twice the maximum supported by the user's display, certain palettes will cause     the function to enter into an infinite loop that reads past the end of an internal heap-allocated buffer.
    The images that trigger this vulnerability are valid per the PNG specification. This vulnerability is     fixed in 1.6.55. (CVE-2026-25646)

  - Improper Input Validation vulnerability in Apache Tomcat Native, Apache Tomcat. When using an OCSP     responder, Tomcat Native (and Tomcat's FFM port of the Tomcat Native code) did not complete verification     or freshness checks on the OCSP response which could allow certificate revocation to be bypassed. This     issue affects Apache Tomcat Native: from 1.3.0 through 1.3.4, from 2.0.0 through 2.0.11; Apache Tomcat:
    from 11.0.0-M1 through 11.0.17, from 10.1.0-M7 through 10.1.51, from 9.0.83 through 9.0.114. The following     versions were EOL at the time the CVE was created but are known to be affected: from 1.1.23 through     1.1.34, from 1.2.0 through 1.2.39. Older EOL versions are not affected. Apache Tomcat Native users are     recommended to upgrade to versions 1.3.5 or later or 2.0.12 or later, which fix the issue. Apache Tomcat     users are recommended to upgrade to versions 11.0.18 or later, 10.1.52 or later or 9.0.115 or later which     fix the issue. (CVE-2026-24734)

  - Issue summary: Calling PKCS12_get_friendlyname() function on a maliciously crafted PKCS#12 file with a     BMPString (UTF-16BE) friendly name containing non-ASCII BMP code point can trigger a one byte write before     the allocated buffer. Impact summary: The out-of-bounds write can cause a memory corruption which can have     various consequences including a Denial of Service. The OPENSSL_uni2utf8() function performs a two-pass     conversion of a PKCS#12 BMPString (UTF-16BE) to UTF-8. In the second pass, when emitting UTF-8 bytes, the     helper function bmp_to_utf8() incorrectly forwards the remaining UTF-16 source byte count as the     destination buffer capacity to UTF8_putc(). For BMP code points above U+07FF, UTF-8 requires three bytes,     but the forwarded capacity can be just two bytes. UTF8_putc() then returns -1, and this negative value is     added to the output length without validation, causing the length to become negative. The subsequent     trailing NUL byte is then written at a negative offset, causing write outside of heap allocated buffer.
    The vulnerability is reachable via the public PKCS12_get_friendlyname() API when parsing attacker-     controlled PKCS#12 files. While PKCS12_parse() uses a different code path that avoids this issue,     PKCS12_get_friendlyname() directly invokes the vulnerable function. Exploitation requires an attacker to     provide a malicious PKCS#12 file to be parsed by the application and the attacker can just trigger a one     zero byte write before the allocated buffer. For that reason the issue was assessed as Low severity     according to our Security Policy. The FIPS modules in 3.6, 3.5, 3.4, 3.3 and 3.0 are not affected by this     issue, as the PKCS#12 implementation is outside the OpenSSL FIPS module boundary. OpenSSL 3.6, 3.5, 3.4,     3.3, 3.0 and 1.1.1 are vulnerable to this issue. OpenSSL 1.0.2 is not affected by this issue.
    (CVE-2025-69419)

  - Vim is an open source, command line text editor. Prior to version 9.1.2132, a heap buffer overflow     vulnerability exists in Vim's tag file resolution logic when processing the 'helpfile' option. The     vulnerability is located in the get_tagfname() function in src/tag.c. When processing help file tags, Vim     copies the user-controlled 'helpfile' option value into a fixed-size heap buffer of MAXPATHL + 1 bytes     (typically 4097 bytes) using an unsafe STRCPY() operation without any bounds checking. This issue has been     patched in version 9.1.2132. (CVE-2026-25749)

  - A Use-After-Free vulnerability has been discovered in GRUB's gettext module. This flaw stems from a     programming error where the gettext command remains registered in memory after its module is unloaded. An     attacker can exploit this condition by invoking the orphaned command, causing the application to access a     memory location that is no longer valid. An attacker could exploit this vulnerability to cause grub to     crash, leading to a Denial of Service. Possible data integrity or confidentiality compromise is not     discarded. (CVE-2025-61662)

The version of tomcat installed on the remote host is prior to 9.0.115-1. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2TOMCAT9-2026-024 advisory.

    mproper Input Validation vulnerability. This issue affects Apache Tomcat: from 11.0.0-M1 through 11.0.14,     from 10.1.0-M1 through 10.1.49, from 9.0.0-M1 through 9.0.112. The following versions were EOL at the time     the CVE was created but are known to be affected: 8.5.0 through 8.5.100. Older EOL versions are not     affected. Tomcat did not validate that the host name provided via the SNI extension was the same as the     host name provided in the HTTP host header field. If Tomcat was configured with more than one virtual host     and the TLS configuration for one of those hosts did not require client certificate authentication but     another one did, it was possible for a client to bypass the client certificate authentication by sending     different host names in the SNI extension and the HTTP host header field. The vulnerability only applies     if client certificate authentication is only enforced at the Connector. It does not apply if client     certificate authentication is enforced at the web application. Users are recommended to upgrade to version     11.0.15 or later, 10.1.50 or later or 9.0.113 or later, which fix the issue. (CVE-2025-66614)

    A flaw was found in Tomcat. An improper input validation vulnerability allows an attacker to bypass     security constraints. Specifically, if a security constraint is configured to permit HEAD requests to a     URI but deny GET requests, a malformed or specification invalid HEAD request using the HTTP/0.9 protocol     can bypass the intended denial rule, enabling an attacker to access resources that should be protected.
    (CVE-2026-24733)

    Improper Input Validation vulnerability in Apache Tomcat Native, Apache Tomcat.

    When using an OCSP responder, Tomcat Native (and Tomcat's FFM port of the Tomcat Native code) did not     complete verification or freshness checks on the OCSP response which could allow certificate revocation to     be bypassed.

    mproper Input Validation vulnerability. This issue affects Apache Tomcat: from 11.0.0-M1 through 11.0.14,     from 10.1.0-M1 through 10.1.49, from 9.0.0-M1 through 9.0.112. The following versions were EOL at the time     the CVE was created but are known to be affected: 8.5.0 through 8.5.100. Older EOL versions are not     affected. Tomcat did not validate that the host name provided via the SNI extension was the same as the     host name provided in the HTTP host header field. If Tomcat was configured with more than one virtual host     and the TLS configuration for one of those hosts did not require client certificate authentication but     another one did, it was possible for a client to bypass the client certificate authentication by sending     different host names in the SNI extension and the HTTP host header field. The vulnerability only applies     if client certificate authentication is only enforced at the Connector. It does not apply if client     certificate authentication is enforced at the web application. Users are recommended to upgrade to version     11.0.15 or later, 10.1.50 or later or 9.0.113 or later, which fix the issue. (CVE-2025-66614)

    A flaw was found in Tomcat. An improper input validation vulnerability allows an attacker to bypass     security constraints. Specifically, if a security constraint is configured to permit HEAD requests to a     URI but deny GET requests, a malformed or specification invalid HEAD request using the HTTP/0.9 protocol     can bypass the intended denial rule, enabling an attacker to access resources that should be protected.

    Improper Input Validation vulnerability in Apache Tomcat Native, Apache Tomcat.

    When using an OCSP responder, Tomcat Native (and Tomcat's FFM port of the Tomcat Native code) did not     complete verification or freshness checks on the OCSP response which could allow certificate revocation to     be bypassed.

  - LIBPNG is a reference library for use in applications that read, create, and manipulate PNG (Portable     Network Graphics) raster image files. Prior to 1.6.55, an out-of-bounds read vulnerability exists in the     png_set_quantize() API function. When the function is called with no histogram and the number of colors in     the palette is more than twice the maximum supported by the user's display, certain palettes will cause     the function to enter into an infinite loop that reads past the end of an internal heap-allocated buffer.
    The images that trigger this vulnerability are valid per the PNG specification. This vulnerability is     fixed in 1.6.55. (CVE-2026-25646)

  - Improper Input Validation vulnerability in Apache Tomcat Native, Apache Tomcat.

  - Issue summary: Calling PKCS12_get_friendlyname() function on a maliciously crafted PKCS#12 file with a     BMPString (UTF-16BE) friendly name containing non-ASCII BMP code point can trigger a one byte write before     the allocated buffer. Impact summary: The out-of-bounds write can cause a memory corruption which can have     various consequences including a Denial of Service. The OPENSSL_uni2utf8() function performs a two-pass     conversion of a PKCS#12 BMPString (UTF-16BE) to UTF-8. In the second pass, when emitting UTF-8 bytes, the     helper function bmp_to_utf8() incorrectly forwards the remaining UTF-16 source byte count as the     destination buffer capacity to UTF8_putc(). For BMP code points above U+07FF, UTF-8 requires three bytes,     but the forwarded capacity can be just two bytes. UTF8_putc() then returns -1, and this negative value is     added to the output length without validation, causing the length to become negative. The subsequent     trailing NUL byte is then written at a negative offset, causing write outside of heap allocated buffer.
    The vulnerability is reachable via the public PKCS12_get_friendlyname() API when parsing attacker-     controlled PKCS#12 files. While PKCS12_parse() uses a different code path that avoids this issue,     PKCS12_get_friendlyname() directly invokes the vulnerable function. Exploitation requires an attacker to     provide a malicious PKCS#12 file to be parsed by the application and the attacker can just trigger a one     zero byte write before the allocated buffer. For that reason the issue was assessed as Low severity     according to our Security Policy. The FIPS modules in 3.6, 3.5, 3.4, 3.3 and 3.0 are not affected by this     issue, as the PKCS#12 implementation is outside the OpenSSL FIPS module boundary. OpenSSL 3.6, 3.5, 3.4,     3.3, 3.0 and 1.1.1 are vulnerable to this issue. OpenSSL 1.0.2 is not affected by this issue.

  - Vim is an open source, command line text editor. Prior to version 9.1.2132, a heap buffer overflow     vulnerability exists in Vim's tag file resolution logic when processing the 'helpfile' option. The     vulnerability is located in the get_tagfname() function in src/tag.c. When processing help file tags, Vim     copies the user-controlled 'helpfile' option value into a fixed-size heap buffer of MAXPATHL + 1 bytes     (typically 4097 bytes) using an unsafe STRCPY() operation without any bounds checking. This issue has been     patched in version 9.1.2132. (CVE-2026-25749)

  - A Use-After-Free vulnerability has been discovered in GRUB's gettext module. This flaw stems from a     programming error where the gettext command remains registered in memory after its module is unloaded. An     attacker can exploit this condition by invoking the orphaned command, causing the application to access a     memory location that is no longer valid. An attacker could exploit this vulnerability to cause grub to     crash, leading to a Denial of Service. Possible data integrity or confidentiality compromise is not     discarded. (CVE-2025-61662)
