CVE-2026-90558 [CRITICAL] – sngrep through 1.8.4 contains stack buffer overflow vulnerabilities in SIP attribute forma

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.
