Description Marian Rehak 2026-09-21 11:04:41 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.

sngrep through 1.8.4 contains stack buffer overflow vulnerabilities in SIP attribute formatting routines when header values exceed the 255-byte buffer limit. Attackers can craft malicious SIP packets with oversized Call-ID, X-Call-ID, or other header fields to overflow stack buffers and cause crashes or execute arbitrary code during packet parsing and rendering.
