The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to integer overflow when reading undo files. A remote attacker can trick the victim to open a specially crafted undo file, trigger integer overflow and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.


2) Integer overflow (CVE-ID: CVE-2017-6349)
