Ubuntu Security Notice USN-2767-1
October 13, 2015

gdk-pixbuf vulnerabilities
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 15.04
- Ubuntu 14.04 LTS
- Ubuntu 12.04 LTS

Summary:

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

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)

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)

Update instructions:

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

Ubuntu 14.04 LTS:
libgdk-pixbuf2.0-0 2.30.7-0ubuntu1.2

Ubuntu 12.04 LTS:
libgdk-pixbuf2.0-0 2.26.1-1ubuntu1.3

After a standard system update you need to restart your session to make
all the necessary changes.
