Overview
Affected versions of this package are vulnerable to Buffer Overflow due to ineffective size check implemented with assert() in the l2filter.c file. An attacker can execute arbitrary code or cause a denial of service by supplying a crafted addr_len value that exceeds the expected maximum, leading to memory corruption during the memcpy operation when assertions are disabled.
