Doc Text:
A flaw was found in PJSIP, a multimedia communication library. A remote attacker could exploit a vulnerability in the `pjsip_multipart_parse()` function when processing incoming Session Initiation Protocol (SIP) messages. This flaw, an out-of-bounds heap read, allows for the disclosure of a small amount of sensitive information from adjacent memory, impacting applications that handle multipart SIP bodies or Session Description Protocol (SDP) content.

Description OSIDB Bzimport 2026-03-20 09:03:11 UTC 
PJSIP is a free and open source multimedia communication library written in C. Versions 2.16 and below have a cascading out-of-bounds heap read in pjsip_multipart_parse(). After boundary string matching, curptr is advanced past the delimiter without verifying it has not reached the buffer end. This allows 1-2 bytes of adjacent heap memory to be read. All applications that process incoming SIP messages with multipart bodies or SDP content are potentially affected. This issue is resolved in version 2.17.
