It has been reported that a buffer overflow condition exists in the Avant Browser software that may cause an attacker to run arbitrary code on a vulnerable host in order to gain unauthorized access to the system. The vulnerability is due to a lack of boundary condition checks on URL values.

This issue may cause an attack to run arbitrary code on a host in the context of the user running the vulnerable version of Avant Browser.
