====================================================================== 4) Description of Vulnerability

Secunia Research has discovered two vulnerabilities in UltraISO, which can be exploited by malicious people to potentially compromise a user's system.

1) A format string error when handling DAA file names can be exploited by tricking a user into opening a file with a specially crafted name containing format specifiers.
