Doc Text:
A flaw was found in PJSIP, a multimedia communication library. A remote attacker could exploit this vulnerability by sending a specially crafted Session Initiation Protocol (SIP) multipart message containing a malformed Content-ID URI. Insufficient length validation during parsing of this URI can lead to an out-of-bounds read, potentially causing a denial of service.

Description OSIDB Bzimport 2026-04-24 19:03:18 UTC 
PJSIP is a free and open source multimedia communication library written in C. In 2.16 and earlier, there is an out-of-bounds read when parsing a malformed Content-ID URI in SIP multipart message body. Insufficient length validation can cause reads beyond the intended buffer bounds. This vulnerability is fixed in 2.17.
