Packages

Details

Gustavo Grieco discovered that the GDK-PixBuf library did not properly
handle scaling tga image files, leading to a heap overflow. If a
user or automated system were tricked into opening a tga image file,
a remote attacker could use this flaw to cause GDK-PixBuf to crash,
resulting in a denial of service, or possibly execute arbitrary code.
