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.
