Description Vladimir Vasilev 2026-10-16 18:37:13 UTC 
Disclaimer: Community trackers are created by Red Hat Product Security team on a best effort basis. Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process.

Sofia-SIP through 1.13.18 contains a heap out-of-bounds read vulnerability in msg_multipart_parse() that allows unauthenticated remote attackers to crash the process by sending oversized MIME boundaries. Attackers can send an INVITE with a multipart Content-Type whose boundary exceeds the body length, causing memcmp to read past the heap buffer and crash the process.
