Short explanation

Sofia-SIP versions contain a heap out-of-bounds read vulnerability in msg_multipart_parse(). Unauthenticated remote attackers can crash the process by sending oversized MIME boundaries.

Why does it matter?

This unauthenticated flaw allows remote attackers to trigger denial-of-service conditions by crashing the affected process.

What should be done?

Follow vendor security advisories

Show the technical text from the sources

Sofia-SIP through 1.13.18 contains a heap out-of-bounds read vulnerability in msg_multipart_parse() that allows unauthenticated remote attackers to crash the process by sending oversized MIME boundaries. Attackers can send an INVITE with a multipart Content-Type whose boundary exceeds the body length, causing memcmp to read past the heap buffer and crash the process.
