========================================================================== Ubuntu Security Notice USN-3085-1 September 21, 2016
gdk-pixbuf vulnerabilities ==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 16.04 LTS - 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:
It was discovered that the GDK-PixBuf library did not properly handle specially crafted bmp images, leading to a heap-based buffer overflow. If a user or automated system were tricked into opening a specially crafted bmp 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. This issue only affected Ubuntu 12.04 LTS and Ubuntu 14.04 LTS. (CVE-2015-7552)
It was discovered that the GDK-PixBuf library contained an integer overflow when handling certain images. If a user or automated system were tricked into opening a crafted 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. This issue only affected Ubuntu 12.04 LTS and Ubuntu 14.04 LTS. (CVE-2015-8875)
Franco Costantini discovered that the GDK-PixBuf library contained an out-of-bounds write error when parsing an ico file. If a user or automated system were tricked into opening a crafted ico file, a remote attacker could use this flaw to cause GDK-PixBuf to crash, resulting in a denial of service. This issue only affected Ubuntu 14.04 LTS and Ubuntu 16.04 LTS. (CVE-2016-6352)
