Details

Tavis Ormandy discovered that libwmf incorrectly used memory after it had
been freed when using its embedded GD library. If a user or automated
system were tricked into opening a crafted WMF file, an attacker could
cause a denial of service or execute arbitrary code with privileges of the
user invoking the program.
