The remote SUSE Linux SLED15 / SLED_SAP15 / SLES15 / SLES_SAP15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2022:4586-1 advisory.

  - A buffer overrun can be triggered in X.509 certificate verification, specifically in name constraint     checking. Note that this occurs after certificate chain signature verification and requires either a CA to     have signed a malicious certificate or for an application to continue certificate verification despite     failure to construct a path to a trusted issuer. An attacker can craft a malicious email address in a     certificate to overflow an arbitrary number of bytes containing the `.' character (decimal 46) on the     stack. This buffer overflow could result in a crash (causing a denial of service). In a TLS client, this     can be triggered by connecting to a malicious server. In a TLS server, this can be triggered if the server     requests client authentication and a malicious client connects. (CVE-2022-3786)

  - If an X.509 certificate contains a malformed policy constraint and policy processing is enabled, then a     write lock will be taken twice recursively. On some operating systems (most widely: Windows) this results     in a denial of service when the affected process hangs. Policy processing being enabled on a publicly     facing server is not considered to be a common setup. Policy processing is enabled by passing the     `-policy' argument to the command line utilities or by calling the `X509_VERIFY_PARAM_set1_policies()'     function. Update (31 March 2023): The description of the policy processing enablement was corrected based     on CVE-2023-0466. (CVE-2022-3996)

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

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2023-051 advisory.

    The BN_mod_sqrt() function, which computes a modular square root, contains a bug that can cause it to loop     forever for non-prime moduli. Internally this function is used when parsing certificates that contain     elliptic curve public keys in compressed form or explicit elliptic curve parameters with a base point     encoded in compressed form. It is possible to trigger the infinite loop by crafting a certificate that has     invalid explicit curve parameters. Since certificate parsing happens prior to verification of the     certificate signature, any process that parses an externally supplied certificate may thus be subject to a     denial of service attack. The infinite loop can also be reached when parsing crafted private keys as they     can contain explicit elliptic curve parameters. Thus vulnerable situations include: - TLS clients     consuming server certificates - TLS servers consuming client certificates - Hosting providers taking     certificates or private keys from customers - Certificate authorities parsing certification requests from     subscribers - Anything else which parses ASN.1 elliptic curve parameters Also any other applications that     use the BN_mod_sqrt() where the attacker can control the parameter values are vulnerable to this DoS     issue. In the OpenSSL 1.0.2 version the public key is not parsed during initial parsing of the certificate     which makes it slightly harder to trigger the infinite loop. However any operation which requires the     public key from the certificate will trigger the infinite loop. In particular the attacker can use a self-     signed certificate to trigger the loop during verification of the certificate signature. This issue     affects OpenSSL versions 1.0.2, 1.1.1 and 3.0. It was addressed in the releases of 1.1.1n and 3.0.2 on the     15th March 2022. Fixed in OpenSSL 3.0.2 (Affected 3.0.0,3.0.1). Fixed in OpenSSL 1.1.1n (Affected     1.1.1-1.1.1m). Fixed in OpenSSL 1.0.2zd (Affected 1.0.2-1.0.2zc). (CVE-2022-0778) (CVE-2022-0778)

    The c_rehash script does not properly sanitise shell metacharacters to prevent command injection. This     script is distributed by some operating systems in a manner where it is automatically executed. On such     operating systems, an attacker could execute arbitrary commands with the privileges of the script. Use of     the c_rehash script is considered obsolete and should be replaced by the OpenSSL rehash command line tool.
    Fixed in OpenSSL 3.0.3 (Affected 3.0.0,3.0.1,3.0.2). Fixed in OpenSSL 1.1.1o (Affected 1.1.1-1.1.1n).
    Fixed in OpenSSL 1.0.2ze (Affected 1.0.2-1.0.2zd). (CVE-2022-1292)

    The function `OCSP_basic_verify` verifies the signer certificate on an OCSP response. In the case where     the (non-default) flag OCSP_NOCHECKS is used then the response will be positive (meaning a successful     verification) even in the case where the response signing certificate fails to verify. It is anticipated     that most users of `OCSP_basic_verify` will not use the OCSP_NOCHECKS flag. In this case the     `OCSP_basic_verify` function will return a negative value (indicating a fatal error) in the case of a     certificate verification failure. The normal expected return value in this case would be 0. This issue     also impacts the command line OpenSSL ocsp application. When verifying an ocsp response with the
    -no_cert_checks option the command line application will report that the verification is successful even     though it has in fact failed. In this case the incorrect successful response will also be accompanied by     error messages showing the failure and contradicting the apparently successful result. Fixed in OpenSSL     3.0.3 (Affected 3.0.0,3.0.1,3.0.2). (CVE-2022-1343)

    The OpenSSL 3.0 implementation of the RC4-MD5 ciphersuite incorrectly uses the AAD data as the MAC key.
    This makes the MAC key trivially predictable. An attacker could exploit this issue by performing a man-in-     the-middle attack to modify data being sent from one endpoint to an OpenSSL 3.0 recipient such that the     modified data would still pass the MAC integrity check. Note that data sent from an OpenSSL 3.0 endpoint     to a non-OpenSSL 3.0 endpoint will always be rejected by the recipient and the connection will fail at     that point. Many application protocols require data to be sent from the client to the server first.
    Therefore, in such a case, only an OpenSSL 3.0 server would be impacted when talking to a non-OpenSSL 3.0     client. If both endpoints are OpenSSL 3.0 then the attacker could modify data being sent in both     directions. In this case both clients and servers could be affected, regardless of the application     protocol. Note that in the absence of an attacker this bug means that an OpenSSL 3.0 endpoint     communicating with a non-OpenSSL 3.0 endpoint will fail to complete the handshake when using this     ciphersuite. The confidentiality of data is not impacted by this issue, i.e. an attacker cannot decrypt     data that has been encrypted using this ciphersuite - they can only modify it. In order for this attack to     work both endpoints must legitimately negotiate the RC4-MD5 ciphersuite. This ciphersuite is not compiled     by default in OpenSSL 3.0, and is not available within the default provider or the default ciphersuite     list. This ciphersuite will never be used if TLSv1.3 has been negotiated. In order for an OpenSSL 3.0     endpoint to use this ciphersuite the following must have occurred: 1) OpenSSL must have been compiled with     the (non-default) compile time option enable-weak-ssl-ciphers 2) OpenSSL must have had the legacy provider     explicitly loaded (either through application code or via configuration) 3) The ciphersuite must have been     explicitly added to the ciphersuite list 4) The libssl security level must have been set to 0 (default is     1) 5) A version of SSL/TLS below TLSv1.3 must have been negotiated 6) Both endpoints must negotiate the     RC4-MD5 ciphersuite in preference to any others that both endpoints have in common Fixed in OpenSSL 3.0.3     (Affected 3.0.0,3.0.1,3.0.2). (CVE-2022-1434)

    The OPENSSL_LH_flush() function, which empties a hash table, contains a bug that breaks reuse of the     memory occuppied by the removed hash table entries. This function is used when decoding certificates or     keys. If a long lived process periodically decodes certificates or keys its memory usage will expand     without bounds and the process might be terminated by the operating system causing a denial of service.
    Also traversing the empty hash table entries will take increasingly more time. Typically such long lived     processes might be TLS clients or TLS servers configured to accept client certificate authentication. The     function was added in the OpenSSL 3.0 version thus older releases are not affected by the issue. Fixed in     OpenSSL 3.0.3 (Affected 3.0.0,3.0.1,3.0.2). (CVE-2022-1473)

    A flaw was found in OpenSSL. The issue in CVE-2022-1292 did not find other places in the `c_rehash` script     where it possibly passed the file names of certificates being hashed to a command executed through the     shell. Some operating systems distribute this script in a manner where it is automatically executed. On     these operating systems, this flaw allows an attacker to execute arbitrary commands with the privileges of     the script. (CVE-2022-2068)

    AES OCB mode for 32-bit x86 platforms using the AES-NI assembly optimized implementation will not encrypt     the entirety of the data under some circumstances. This could reveal sixteen bytes of data that was     preexisting in the memory that wasn't written. In the special case of in place encryption, sixteen bytes     of the plaintext would be revealed. (CVE-2022-2097)

    A buffer overrun can be triggered in X.509 certificate verification, specifically in name constraint     checking. Note that this occursafter certificate chain signature verification and requires either a CA to     have signed the malicious certificate or for the application to continue certificate verification despite     failure to construct a path to a trusted issuer. An attacker can craft a malicious email address to     overflow four attacker-controlled bytes on the stack. This buffer overflow could result in a crash     (causing a denial of service) or potentially remote code execution.. (CVE-2022-3602)

An attacker can craft a malicious email address to     overflow four attacker-controlled bytes on the stack. This buffer overflow could result in a crash     (causing a denial of service) or potentially remote code execution. Many platforms implement stack     overflow protections which would mitigate against the risk of remote code execution. The risk may be     further mitigated based on stack layout for any given platform/compiler. Pre-announcements of     CVE-2022-3602 described this issue as CRITICAL. Further analysis based on some of the mitigating factors     described above have led this to be downgraded to HIGH. Users are still encouraged to upgrade to a new     version as soon as possible. In a TLS client, this can be triggered by connecting to a malicious server.
    In a TLS server, this can be triggered if the server requests client authentication and a malicious client     connects. (CVE-2022-3602)
