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.
2) A format string error when handling ISZ file names can be exploited
by tricking a user into opening a file with a specially crafted name
containing format specifiers.
Successful exploitation may allow execution of arbitrary code.
