CVE-2023-32307

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.
