Details

Wooseok Kang discovered that PLIB did not properly manage memory under
certain circumstances. If a user were tricked into opening a specially
crafted TGA file, an attacker could possibly use this issue to cause
applications using PLIB to crash, resulting in a denial of service, or
possibly execute arbitrary code.
