NVD Description

Note: Versions mentioned in the description apply only to the upstream asterisk package and not the asterisk package as distributed by Debian. See How to fix? for Debian:unstable relevant fixed versions and status.

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.
