Description Vladimir Vasilev 2026-09-14 07:13:54 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.

SIPp through 3.7.7 contains a buffer overflow vulnerability in get_peer_tag() function when processing SIP To headers with tag parameters of 2049 bytes or more. Unauthenticated remote attackers can send crafted SIP messages with oversized tag parameters to overflow the static buffer and crash the process.
