"The version of AHV installed on the remote host is prior to 10.0.1.4. It is, therefore, affected by multiple
vulnerabilities as referenced in the NXSA-AHV-10.0.1.4 advisory.

  - There exists a vulnerability in SQLite versions before 3.50.2 where the number of aggregate terms could
    exceed the number of columns available. This could lead to a memory corruption issue. We recommend
    upgrading to version 3.50.2 or above. (CVE-2025-6965)

  - The regcomp function in the GNU C library version from 2.4 to 2.41 is subject to a double free if some
    previous allocation fails. It can be accomplished either by a malloc failure or by using an interposed
    malloc that injects random malloc failures. The double free can allow buffer manipulation depending of how
    the regex is constructed. This issue affects all architectures and ABIs supported by the GNU C library.
    (CVE-2025-8058)

  - A multi-vendor cache poisoning vulnerability named 'Rebirthday Attack' has been discovered in caching
    resolvers that support EDNS Client Subnet (ECS). Unbound is also vulnerable when compiled with ECS
    support, i.e., '--enable-subnet', AND configured to send ECS information along with queries to upstream
    name servers, i.e., at least one of the 'send-client-subnet', 'client-subnet-zone' or 'client-subnet-
    always-forward' options is used. Resolvers supporting ECS need to segregate outgoing queries to
    accommodate for different outgoing ECS information. This re-opens up resolvers to a birthday paradox
    attack (Rebirthday Attack) that tries to match the DNS transaction ID in order to cache non-ECS poisonous
    replies. (CVE-2025-5994)

  - Perl threads have a working directory race condition where file operations may target unintended paths. If
    a directory handle is open at thread creation, the process-wide current working directory is temporarily
    changed in order to clone that handle for the new thread, which is visible from any third (or more) thread
    already running. This may lead to unintended operations such as loading code or accessing files from
    unexpected locations, which a local attacker may be able to exploit. The bug was introduced in commit
    11a11ecf4bea72b17d250cfb43c897be1341861e and released in Perl version 5.13.6 (CVE-2025-40909)

  - In libxml2 before 2.13.8 and 2.14.x before 2.14.2, xmlSchemaIDCFillNodeTables in xmlschemas.c has a heap-
    based buffer under-read. To exploit this, a crafted XML document must be validated against an XML schema
    with certain identity constraints, or a crafted XML schema must be used. (CVE-2025-32415)

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