Discussion

ITalk Plus Multiple Remote Pre-Authentication Buffer Overflow Vulnerabilities

Italk Plus is prone to multiple remote buffer-overflow vulnerabilities because the application fails to properly bounds-check user-supplied input before copying it to insufficiently sized memory buffers.

Exploiting these issues allows remote, unauthenticated attackers to execute arbitrary machine code in the context of affected servers. This may facilitate the compromise of affected computers.

Versions of Italk Plus prior to 0.92.1 are vulnerable to these issues.
