Name of the Vulnerable Software and Affected Versions ALGO 8180 IP Audio Alerter (affected versions not specified)

Description A flaw exists in the handling of the Alert-Info header within SIP INVITE requests. The issue stems from insufficient validation of user-supplied data length before copying it into a fixed-length stack-based buffer. This allows a remote attacker to execute arbitrary code on affected devices without authentication. The vulnerable component is the processing of the Alert-Info header in the SIP INVITE request.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
