wire-avs provides Audio, Visual, and Signaling (AVS) functionality sure the secure messaging software Wire. Prior to versions 9.2.22 and 9.3.5, a remote format string vulnerability could potentially allow an attacker to cause a denial of service or possibly execute arbitrary code. The issue has been fixed in wire-avs 9.2.22 & 9.3.5 and is already included on all Wire products. No known workarounds are available.
