Detailsinfo

A vulnerability classified as critical has been found in GD Graphics Library up to 2.2.3 (Image Processing Software). This affects an unknown functionality of the file gd_io.c. The manipulation with an unknown input leads to a integer overflow vulnerability. CWE is classifying the issue as CWE-190. The product performs a calculation that can produce an integer overflow or wraparound, when the logic assumes that the resulting value will always be larger than the original value. This can introduce other weaknesses when the calculation is used for resource management or execution control. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

Integer overflow in gd_io.c in the GD Graphics Library (aka libgd) before 2.2.4 allows remote attackers to have unspecified impact via vectors involving the number of horizontal and vertical chunks in an image.

The bug was discovered 01/28/2017. The weakness was disclosed 03/15/2017 by Salvatore Bonaccorso (oss-sec). It is possible to read the advisory at openwall.com. This vulnerability is uniquely identified as CVE-2016-10168 since 01/28/2017. The exploitability is told to be easy. 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 vulnerability was handled as a non-public zero-day exploit for at least 25 days. During that time the estimated underground price was around $5k-$25k. The vulnerability scanner Nessus provides a plugin with the ID 97369 (openSUSE Security Update : gd (openSUSE-2017-289)), 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 169714 (SUSE Enterprise Linux Security Update for gd (SUSE-SU-2017:0468-1)).
