Detailsinfo

A vulnerability classified as very critical was found in Samsung Galaxy S6 (Smartphone Operating System). Affected by this vulnerability is some unknown processing of the component JPEG Image Handler. The manipulation with an unknown input leads to a memory corruption vulnerability. The CWE definition for the vulnerability is 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. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

The DCMProvider service in Samsung LibQjpeg on a Samsung SM-G925V device running build number LRX22G.G925VVRU1AOE2 allows remote attackers to cause a denial of service (segmentation fault and process crash) and execute arbitrary code via a crafted JPG.

The weakness was disclosed 11/03/2015 as File 134197 (Packetstorm). The advisory is shared at packetstormsecurity.com. This vulnerability is known as CVE-2015-7894 since 10/22/2015. The attack can be launched remotely. The exploitation doesn't need any form of authentication. Technical details are unknown but a public exploit is available.
