Overview

Affected versions of this package are vulnerable to Buffer Overflow due to the improper handling of the SWERR and OVERFLOW bits during writeback operations. An attacker can cause a buffer overflow by exploiting the way the current code overwrites these bits without properly preserving their states after a register read.
