CVE-2015-7552

Heap-based buffer overflow in the gdk_pixbuf_flip function in gdk-pixbuf-scale.c in gdk-pixbuf 2.30.x allows remote attackers to cause a denial of service or possibly execute arbitrary code via a crafted BMP file.

Heap-based buffer overflow in the gdk_pixbuf_flip function in gdk-pixbuf-scale.c in gdk-pixbuf 2.30.x allows remote attackers to cause a denial of service or possibly execute arbitrary code via a crafted BMP file.

These are all security issues fixed in the gdk-pixbuf-devel-2.36.0-1.1 package on the GA media of openSUSE Tumbleweed.

This update for gdk-pixbuf fixes the following security issues:

• CVE-2015-7552: various overflows, including heap overflow in flipping bmp files (bsc#958963)

The following non-security issue was fixed:

• bsc#960155: fix a possible divide by zero

This update for gdk2 fixes the following security issues:

• CVE-2015-7552: various overflows, including heap overflow in flipping bmp files (bsc#958963)

The following non-security issues were fixed:

• bsc#960155: fix a possible divide by zero

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)
