CVSS v3.1
9.8
Critical
| Vector | AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H |
Name of the Vulnerable Software and Affected Versions
PJSIP versions prior to 2.13.1
Description
The issue is related to a buffer overread that can occur when parsing a specially crafted STUN message with an unknown attribute. This can affect applications that use STUN, including PJNATH and PJSUA-LIB. Exploitation of this issue may allow a remote attacker to send a specially crafted STUN message, causing a heap buffer overflow and potentially allowing the execution of arbitrary code on the target system.
Recommendations
For versions prior to 2.13.1, update to version 2.13.1 or later to resolve the issue. As a temporary workaround, consider restricting the handling of STUN messages with unknown attributes until a patch is applied.
