This update for apache2 fixes the following issues :

  - CVE-2018-1283: when mod_session is configured to forward     its session data to CGI applications (SessionEnv on, not     the default), a remote user may influence their content     by using a \'Session\' header leading to unexpected     behavior [bsc#1086814].

  - CVE-2018-1301: due to an out of bound access after a     size limit being reached by reading the HTTP header, a     specially crafted request could lead to remote denial of     service. [bsc#1086817]

  - CVE-2018-1303: a specially crafted HTTP request header     could lead to crash due to an out of bound read while     preparing data to be cached in shared     memory.[bsc#1086813]

  - CVE-2017-15715: a regular expression could match '$' to     a newline character in a malicious filename, rather than     matching only the end of the filename. leading to     corruption of uploaded files.[bsc#1086774]

  - CVE-2018-1312: when generating an HTTP Digest     authentication challenge, the nonce sent to prevent     reply attacks was not correctly generated using a     pseudo-random seed. In a cluster of servers using a     common Digest authentication configuration, HTTP     requests could be replayed across servers by an attacker     without detection. [bsc#1086775]

  - CVE-2017-15710: mod_authnz_ldap, if configured with     AuthLDAPCharsetConfig, uses the Accept-Language header     value to lookup the right charset encoding when     verifying the user's credentials. If the header value is     not present in the charset conversion table, a fallback     mechanism is used to truncate it to a two characters     value to allow a quick retry (for example, 'en-US' is     truncated to 'en'). A header value of less than two     characters forces an out of bound write of one NUL byte     to a memory location that is not part of the string. In     the worst case, quite unlikely, the process would crash     which could be used as a Denial of Service attack. In     the more likely case, this memory is already reserved     for future use and the issue has no effect at all.

    [bsc#1086820]

  - CVE-2018-1302: when an HTTP/2 stream was destroyed after     being handled, it could have written a NULL pointer     potentially to an already freed memory. The memory pools     maintained by the server make this vulnerability hard to     trigger in usual configurations, the reporter and the     team could not reproduce it outside debug builds, so it     is classified as low risk.

  - *Low*: Possible out of bound access after failure in     reading the HTTP request (CVE-2018-1301)

  - *Low*: Weak Digest auth nonce generation in     mod_auth_digest (CVE-2018-1312)

  - *Low*: <FilesMatch> bypass with a trailing newline in     the file name (CVE-2017-15715)

  - *Low*: Out of bound write in mod_authnz_ldap when using     too small Accept-Language values (CVE-2017-15710)

  - *Moderate*: Tampering of mod_session data for CGI     applications (CVE-2018-1283)

The remote Redhat Enterprise Linux 6 / 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2019:0367 advisory.

    Red Hat JBoss Core Services is a set of supplementary software for Red Hat JBoss middleware products. This     software, such as Apache HTTP Server, is common to multiple JBoss middleware products, and is packaged     under Red Hat JBoss Core Services to allow for faster distribution of updates, and for a more consistent     update experience.

    This release of Red Hat JBoss Core Services Apache HTTP Server 2.4.29 Service Pack 1 serves as an update     to Red Hat JBoss Core Services Apache HTTP Server 2.4.29, and includes bug fixes for CVEs which are linked     to in the References section.

    Security Fixes:

    * httpd: DoS for HTTP/2 connections by continuous SETTINGS (CVE-2018-11763)

    * httpd: Weak Digest auth nonce generation in mod_auth_digest     (CVE-2018-1312)

    * httpd: Out of bound access after failure in reading the HTTP request     (CVE-2018-1301)

    * httpd: Use-after-free on HTTP/2 stream shutdown (CVE-2018-1302)

    * httpd: <FilesMatch> bypass with a trailing newline in the file name     (CVE-2017-15715)

    * httpd: Out of bound write in mod_authnz_ldap when using too small     Accept-Language values (CVE-2017-15710)

    * httpd: Out of bounds read in mod_cache_socache can allow a remote     attacker to cause a denial of service (CVE-2018-1303)

    * httpd: Improper handling of headers in mod_session can allow a remote     user to modify session data for CGI applications (CVE-2018-1283)

    * httpd: mod_http2: too much time allocated to workers, possibly leading to     DoS (CVE-2018-1333)

    * mod_jk: connector path traversal due to mishandled HTTP requests in httpd     (CVE-2018-11759)

    * nghttp2: Null pointer dereference when too large ALTSVC frame is received     (CVE-2018-1000168)

    * openssl: Handling of crafted recursive ASN.1 structures can cause a stack     overflow and resulting denial of service (CVE-2018-0739)

    Details around each issue, including information about the CVE, severity of     the issue, and the CVSS score, can be found on the CVE pages listed in the     Reference section below.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux 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 AOS installed on the remote host is prior to 5.19.1. It is, therefore, affected by multiple vulnerabilities as referenced in the NXSA-AOS-5.19.1 advisory.

  - In Network Security Services (NSS) before 3.46, several cryptographic primitives had missing length     checks. In cases where the application calling the library did not perform a sanity check on the inputs it     could result in a crash due to a buffer overflow. (CVE-2019-17006)

  - Heap buffer overflow in the TFTP protocol handler in cURL 7.19.4 to 7.65.3. (CVE-2019-5482)

  - In all versions of cpio before 2.13 does not properly validate input files when generating TAR archives.
    When cpio is used to create TAR archives from paths an attacker can write to, the resulting archive may     contain files with permissions the attacker did not have or in paths he did not have access to. Extracting     those archives from a high-privilege user without carefully reviewing them may lead to the compromise of     the system. (CVE-2019-14866)

  - If an HTTP/2 client connecting to Apache Tomcat 10.0.0-M1 to 10.0.0-M7, 9.0.0.M1 to 9.0.37 or 8.5.0 to     8.5.57 exceeded the agreed maximum number of concurrent streams for a connection (in violation of the     HTTP/2 protocol), it was possible that a subsequent request made on that connection could contain HTTP     headers - including HTTP/2 pseudo headers - from a previous request rather than the intended headers. This     could lead to users seeing responses for unexpected resources. (CVE-2020-13943)

  - Vulnerability in the MySQL Server product of Oracle MySQL (component: Server: Optimizer). Supported     versions that are affected are 5.6.45 and prior, 5.7.27 and prior and 8.0.17 and prior. Easily exploitable     vulnerability allows low privileged attacker with network access via multiple protocols to compromise     MySQL Server. Successful attacks of this vulnerability can result in unauthorized ability to cause a hang     or frequently repeatable crash (complete DOS) of MySQL Server. (CVE-2019-2974)

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