Hi,
The following vulnerability was published for sofia-sip.
CVE-2023-22741[0]:
| 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.
