Name of the Vulnerable Software and Affected Versions Kamailio versions prior to 4.3.5

Description The issue is related to a heap-based buffer overflow in the encode msg function, located in the encode msg.c file of the SEAS module. This overflow can be triggered by a large SIP packet, allowing remote attackers to cause a denial of service, which includes memory corruption and process crash, or possibly execute arbitrary code.

Recommendations For versions prior to 4.3.5, update to version 4.3.5 or later to resolve the issue. As a temporary workaround, consider restricting the size of incoming SIP packets to prevent exploitation of the encode msg function in the SEAS module.
