"The version of AHV installed on the remote host is prior to 10.3.1.10. It is, therefore, affected by multiple
vulnerabilities as referenced in the NXSA-AHV-10.3.1.10 advisory.

  - A flaw was found in GLib (Gnome Lib). This vulnerability allows a remote attacker to cause heap
    corruption, leading to a denial of service or potential code execution via a buffer-underflow in the
    GVariant parser when processing maliciously crafted input strings. (CVE-2025-14087)

  - In MIT Kerberos 5 (aka krb5) before 1.22.3, there is a NULL pointer dereference if an application calls
    gss_accept_sec_context() on a system with a NegoEx mechanism registered in /etc/gss/mech. An
    unauthenticated remote attacker can trigger this, causing the process to terminate in parse_nego_message.
    (CVE-2026-40355)

  - In MIT Kerberos 5 (aka krb5) before 1.22.3, there is an integer underflow and resultant out-of-bounds read
    if an application calls gss_accept_sec_context() on a system with a NegoEx mechanism registered in
    /etc/gss/mech. An unauthenticated remote attacker can trigger this, possibly causing the process to
    terminate in parse_message. (CVE-2026-40356)

  - In rsync 3.0.1 through 3.4.1, receive_xattr relies on an untrusted length value during a qsort call,
    leading to a receiver use-after-free. The victim must run rsync with -X (aka --xattrs). On Linux, many
    (but not all) common configurations are vulnerable. Non-Linux platforms are more widely vulnerable.
    (CVE-2026-41035)

  - An issue was discovered in libsndfile 1.2.2 IMA ADPCM codec. The AIFF code path (line 241) was fixed with
    (sf_count_t) cast, but the WAV code path (line 235) and close path (line 167) were not. When
    samplesperblock (int) * blocks (int) exceeds INT_MAX, the 32-bit multiplication overflows before being
    assigned to sf.frames (sf_count_t/int64). With samplesperblock=50000 and blocks=50000, the product
    2500000000 overflows to -1794967296. This causes incorrect frame count leading to heap buffer overflow or
    denial of service. Both values come from the WAV file header and are attacker-controlled. This issue was
    discovered after an incomplete fix for CVE-2022-33065. (CVE-2026-37555)

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