Summary

GDK-PixBuf could be made to crash or run programs as your login if it

opened a specially crafted file.

Software Description:

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.

(CVE-2015-7673)
