CWE-122
Exploitation vector: Network
Exploit availability: No
Vulnerable software:
ImageMagick
Client/Desktop applications /

Description
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error in The WPG parser in ImageMagick before 6.9.4-4 and 7.x before 7.0.1-5, when a memory limit is set,. A remote attacker can use vectors related to the SetImageExtent return-value check to trigger heap-based buffer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
