CVE-2016-6207

Integer overflow in the _gdContributionsAlloc function in gd_interpolation.c in GD Graphics Library (aka libgd) before 2.2.3 allows remote attackers to cause a denial of service (out-of-bounds memory write or memory consumption) via unspecified vectors.

Integer overflow in the _gdContributionsAlloc function in gd_interpolation.c in GD Graphics Library (aka libgd) before 2.2.3 allows remote attackers to cause a denial of service (out-of-bounds memory write or memory consumption) via unspecified vectors.

Updated libgd packages fix security vulnerabilities:

A read out-of-bounds was found in the parsing of TGA files when the header reports an incorrect size (CVE-2016-6132) or invalid bpp (CVE-2016-6214) or RLE value (upstream issue 248).

Integer overflow error within _gdContributionsAlloc() (CVE-2016-6207).

A regression in the previous update that caused some packages to fail to build against libgd has also been fixed (mga#18947).

These are all security issues fixed in the gd-2.2.3-2.1 package on the GA media of openSUSE Tumbleweed.

It was discovered that the GD library incorrectly handled certain malformed TGA images. If a user or automated system were tricked into processing a specially crafted TGA image, an attacker could cause a denial of service. (CVE-2016-6132, CVE-2016-6214)

It was discovered that the GD library incorrectly handled memory when using gdImageScale(). A remote attacker could possibly use this issue to cause a denial of service or possibly execute arbitrary code. (CVE-2016-6207)
