"The remote Debian 10 host has packages installed that are affected by a vulnerability as referenced in the dla-3292
advisory.

  - Sofia-SIP is an open-source SIP User-Agent library, compliant with the IETF RFC3261 specification. In
    affected versions Sofia-SIP **lacks both message length and attributes length checks** when it handles
    STUN packets, leading to controllable heap-over-flow. For example, in stun_parse_attribute(), after we get
    the attribute's type and length value, the length will be used directly to copy from the heap, regardless
    of the message's left size. Since network users control the overflowed length, and the data is written to
    heap chunks later, attackers may achieve remote code execution by heap grooming or other exploitation
    methods. The bug was introduced 16 years ago in sofia-sip 1.12.4 (plus some patches through 12/21/2006) to
    in tree libs with git-svn-id: http://svn.freeswitch.org/svn/freeswitch/trunk@3774
    d0543943-73ff-0310-b7d9-9358b9ac24b2. Users are advised to upgrade. There are no known workarounds for
    this vulnerability. (CVE-2023-22741)

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