4Description
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.
Analysis
PJSIP versions 2.16 and below contain a cascading out-of-bounds heap read vulnerability in the pjsip_multipart_parse() function that allows attackers to read 1-2 bytes of adjacent heap memory when processing SIP messages with multipart bodies or SDP content. The vulnerability affects all applications using PJSIP to process incoming SIP messages, as the flaw does not require authentication or user interaction and can be triggered remotely over the network. …
