Description:
A vulnerability has been discovered in SonicWALL GLobal VPN Client, which potentially can be exploited by malicious people to compromise a user's system.
The vulnerability is caused due to a format-string error when processing a VPN configuration file.

Successful exploitation may allow execution of arbitrary code.
