A vulnerability was found in LibTIFF 4.0/4.0.1/4.0.2 (Image Processing Software). It has been classified as critical. This affects an unknown code of the file gif2tiff.c of the component Raster File Count Handler. The manipulation with an unknown input leads to a memory corruption vulnerability. CWE is classifying the issue as CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

Multiple buffer overflows in libtiff before 4.0.3 allow remote attackers to cause a denial of service (out-of-bounds write) via a crafted (1) extension block in a GIF image or (2) GIF raster image to tools/gif2tiff.c or (3) a long filename for a TIFF image to tools/rgb2ycbcr.c. NOTE: vectors 1 and 3 are disputed by Red Hat, which states that the input cannot exceed the allocated buffer size.

The weakness was released 08/01/2013 by Pedro Ribeiro as Four (stack-based) buffer overflows and one use-after-free in libtiff v4.0.3 as not defined mailinglist post (oss-sec). It is possible to read the advisory at seclists.org. The vendor was not involved in the public release. This vulnerability is uniquely identified as CVE-2013-4231 since 06/12/2013. The exploitability is told to be difficult. It is possible to initiate the attack remotely. No form of authentication is needed for exploitation. Technical details of the vulnerability are known, but there is no available exploit.

The real existence of this vulnerability is still doubted at the moment. The vulnerability scanner Nessus provides a plugin with the ID 75146 (openSUSE Security Update : tiff (openSUSE-SU-2013:1482-1)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family SuSE Local Security Checks. The commercial vulnerability scanner Qualys is able to test this issue with plugin 350364 (Amazon Linux Security Advisory for libtiff: ALAS-2014-365).

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.

The vulnerability is also documented in the databases at X-Force (86305) and Tenable (75146). Further details are available at asmail.be. Entries connected to this vulnerability are available at 9947, 9948, 9949 and 9950.
