Description Preview
The vulnerability is a stack-based buffer overflow in the nestlex function in nestlex.c in Socat 1.5.0.0 through 1.7.1.2 and 2.0.0-b1 through 2.0.0-b3. When bidirectional data relay is enabled, it allows context-dependent attackers to execute arbitrary code via long command-line arguments. This vulnerability can potentially allow an attacker to execute arbitrary code on the affected system, leading to unauthorized access or disruption of service.
