Vulnerability details

The vulnerability allows a remote attacker to disclose sensitive information or cause a denial of service.

The vulnerability exists due to out-of-bounds read in the RTCP SDES packet parser when parsing crafted RTCP packets with invalid SDES data. A remote attacker can send a specially crafted RTCP packet to disclose sensitive information or cause a denial of service.

The issue involves missing bounds validation when iterating over SDES items and entries, and an incorrect packet length calculation that underestimates the total packet size by 4 bytes.
