Description

This security bulletin contains information about 1 vulnerability.


1) Off-by-one (CVE-ID: CVE-2026-57160)

CWE-ID: CWE-193 - Off-by-one Error

CVSSv4: 6.9 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N]


The vulnerability allows a remote attacker to cause a denial of service.

The vulnerability exists due to an off-by-one error in pjsip_generic_array_hdr_print() in pjsip/src/pjsip/sip_msg.c when serializing generic array headers while re-serializing incoming SIP requests. A remote attacker can send a specially crafted SIP request to cause a denial of service.

This is primarily reachable in applications such as proxies, SBCs, or B2BUAs that parse and re-serialize incoming SIP messages.
