========================================================================== Ubuntu Security Notice USN-2767-1 October 13, 2015
A security issue affects these releases of Ubuntu and its derivatives:
GDK-PixBuf could be made to crash or run programs as your login if it opened a specially crafted file.
Software Description: - gdk-pixbuf: GDK Pixbuf library
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)
Gustavo Grieco discovered that the GDK-PixBuf library contained an integer overflow when handling certain GIF images. If a user or automated system were tricked into opening a GIF 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-2015-7674)
The problem can be corrected by updating your system to the following package versions:
Ubuntu 15.04: libgdk-pixbuf2.0-0 2.31.3-1ubuntu0.2
