CVE-2022-47516

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 stun_parse_attr_error_code and stun_parse_attr_uint32 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 attr_type 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)

The config_sortlist function is missing checks about the validity of the input string, which allows a possible arbitrary length stack overflow and thus may cause a denial of service. (CVE-2022-47516)

It was discovered that Sofia-SIP incorrectly handled specially crafted SDP packets. A remote attacker could use this issue to cause applications using Sofia-SIP to crash, leading to a denial of service, or possibly execute arbitrary code. This issue only affected Ubuntu 16.04 ESM, Ubuntu 18.04 LTS, Ubuntu 20.04 LTS and Ubuntu 22.04 LTS. (CVE-2022-31001, CVE-2022-31002, CVE-2022-31003)
