Detailsinfo

A vulnerability was found in gdk-pixbuf (version unknown) and classified as problematic. Affected by this issue is an unknown function of the file io-ico.c of the component ICO File Handler. The manipulation with an unknown input leads to a integer overflow vulnerability. Using CWE to declare the problem leads to 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. Impacted is availability. CVE summarizes:

Integer overflow in io-ico.c in gdk-pixbuf allows context-dependent attackers to cause a denial of service (segmentation fault and application crash) via a crafted image entry offset in an ICO file, which triggers an out-of-bounds read, related to compiler optimizations.

The bug was discovered 02/21/2017. The weakness was published 03/10/2017 by Ariel Zelivansky (Website). The advisory is available at mov.sx. This vulnerability is handled as CVE-2017-6312 since 02/23/2017. The attack may be launched remotely. No form of authentication is required for exploitation. Technical details are known, but there is no available exploit.

The vulnerability was handled as a non-public zero-day exploit for at least 16 days. During that time the estimated underground price was around $0-$5k. The vulnerability scanner Nessus provides a plugin with the ID 102990 (SUSE SLED12 / SLES12 Security Update : gdk-pixbuf (SUSE-SU-2017:2381-1)), 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 197020 (Ubuntu Security Notification for Gdk-pixbuf Vulnerabilities (USN-3532-1)).

Upgrading eliminates this vulnerability. A possible mitigation has been published 7 months after the disclosure of the vulnerability.
