Sofia SIP is a RFC-3261-compliant library for SIP user agents and other network elements. The Session Initiation Protocol (SIP) is an application-layer control (signaling) protocol for creating, modifying, and terminating sessions with one or more participants. These sessions include Internet telephone calls, multimedia distribution, and multimedia conferences.

Security Fix(es):

An issue was discovered in the libsofia-sip fork in drachtio-server before 0.8.20. It allows remote attackers to cause a denial of service (daemon crash) via a crafted UDP message that leads to a failure of the libsofia-sip-ua/tport/tport.c self assertion.(CVE-2022-47516)

Sofia-SIP is an open-source SIP User-Agent library, compliant with the IETF RFC3261 specification. Referring to GHSA-8599-x7rq-fr54, several other potential heap-over-flow and integer-overflow in stunparseattrerrorcode and stunparseattruint32 were found because the lack of attributes length check when Sofia-SIP handles STUN packets. The previous patch of GHSA-8599-x7rq-fr54 fixed the vulnerability when attrtype did not match the enum value, but there are also vulnerabilities in the handling of other valid cases. The OOB read and integer-overflow made by attacker may lead to crash, high consumption of memory or even other more serious consequences. These issue have been addressed in version 1.13.15. Users are advised to upgrade.(CVE-2023-32307)
