Detailsinfo

A vulnerability, which was classified as critical, has been found in LibTIFF 4.0/4.0.1/4.0.2 (Image Processing Software). This issue affects an unknown function of the file gif2tiff.c of the component GIF Raster File Datasize Handler. The manipulation with an unknown input leads to a memory corruption vulnerability. Using CWE to declare the problem leads to 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. Impacted is 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 disclosed 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. The identification of this vulnerability is CVE-2013-4231 since 06/12/2013. The exploitation is known to be difficult. The attack may be initiated remotely. No form of authentication is needed for a successful 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 and running in the context l. The commercial vulnerability scanner Qualys is able to test this issue with plugin 350364 (Amazon Linux Security Advisory for libtiff: ALAS-2014-365).

Upgrading eliminates this vulnerability. A possible mitigation has been published 2 months after the disclosure of the vulnerability.

The vulnerability is also documented in the databases at Tenable (75146), SecurityFocus (BID 61695†), OSVDB (96203†) and Secunia (SA54543†). asmail.be is providing further details. The entries VDB-9948, VDB-9949, VDB-9950 and VDB-9951 are pretty similar. If you want to get the best quality for vulnerability data then you always have to consider VulDB.
