SafeNet SoftRemote is an IPsec VPN client that sets up a secure channel for data transport. The application is a popular VPN client which has been OEM’d by many other companies. As a result this vulnerability affects a number of products and vendors.

SafeNet SoftRemote is vulnerable to a local stack based buffer overflow which can lead to the compromise of a vulnerable system.


The vulnerability is caused due to a boundary error when processing certain sections of spd (policy) files. Passing an overly long string to either “TREENAME” or “GROUPNAME” will trigger the overflow. Successful exploitation results in the execution of arbitrary code.
