wire-avs is the audio visual signaling (AVS) component of Wire, an open-source messenger. A remote format string vulnerability in versions prior to 7.1.12 allows an attacker to cause a denial of service or possibly execute arbitrary code. The issue has been fixed in wire-avs 7.1.12. There are currently no known workarounds.

Weakness

The product uses a function that accepts a format string as an argument, but the format string originates from an external source.
