Hi,

The following vulnerability was published for sofia-sip.

CVE-2023-32307[0]:
| Sofia-SIP is an open-source SIP User-Agent library, compliant with the
| IETF RFC3261 specification. Referring to [GHSA-8599-x7rq-
| fr54](https://github.com/freeswitch/sofia-
| sip/security/advisories/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](https://github.com/freeswitch/sofia-
| sip/security/advisories/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.


If you fix the vulnerability please also make sure to include the
