"The version of AHV installed on the remote host is prior to 10.3.1.2 / AHV-10.3.1.2. It is, therefore, affected by
multiple vulnerabilities as referenced in the NXSA-AHV-10.3.1.2 advisory.

  - A heap-buffer-overflow (off-by-one) flaw was found in the GnuTLS software in the template parsing logic
    within the certtool utility. When it reads certain settings from a template file, it allows an attacker to
    cause an out-of-bounds (OOB) NULL pointer write, resulting in memory corruption and a denial-of-service
    (DoS) that could potentially crash the system. (CVE-2025-32990)

  - A flaw was found in GnuTLS. A double-free vulnerability exists in GnuTLS due to incorrect ownership
    handling in the export logic of Subject Alternative Name (SAN) entries containing an otherName. If the
    type-id OID is invalid or malformed, GnuTLS will call asn1_delete_structure() on an ASN.1 node it does not
    own, leading to a double-free condition when the parent function or caller later attempts to free the same
    structure. This vulnerability can be triggered using only public GnuTLS APIs and may result in denial of
    service or memory corruption, depending on allocator behavior. (CVE-2025-32988)

  - A NULL pointer dereference flaw was found in the GnuTLS software in _gnutls_figure_common_ciphersuite().
    (CVE-2025-6395)

  - Vim is an open source, command line text editor. Prior to version 9.1.1552, a path traversal issue in
    Vim's tar.vim plugin can allow overwriting of arbitrary files when opening specially crafted tar archives.
    Impact is low because this exploit requires direct user interaction. However, successfully exploitation
    can lead to overwriting sensitive files or placing executable code in privileged locations, depending on
    the permissions of the process editing the archive. The victim must edit such a file using Vim which will
    reveal the filename and the file content, a careful user may suspect some strange things going on.
    Successful exploitation could results in the ability to execute arbitrary commands on the underlying
    operating system. Version 9.1.1552 contains a patch for the vulnerability. (CVE-2025-53905)

  - Vim is an open source, command line text editor. Prior to version 9.1.1551, a path traversal issue in
    Vim's zip.vim plugin can allow overwriting of arbitrary files when opening specially crafted zip archives.
    Impact is low because this exploit requires direct user interaction. However, successfully exploitation
    can lead to overwriting sensitive files or placing executable code in privileged locations, depending on
    the permissions of the process editing the archive. The victim must edit such a file using Vim which will
    reveal the filename and the file content, a careful user may suspect some strange things going on.
    Successful exploitation could results in the ability to execute arbitrary commands on the underlying
    operating system. Version 9.1.1551 contains a patch for the vulnerability. (CVE-2025-53906)

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