CVE-2023-22741

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.
