rofl0r/proxychains-ng <= 4.17 Stack-based Buffer Overflow
Summary
rofl0r/proxychains-ng <= 4.17 Stack-based Buffer Overflow
Original description
The description as published by the source.
rofl0r/proxychains-ng versions up to and including 4.17 and prior to commit cc005b7 contain a stack-based buffer overflow vulnerability in the function proxy_from_string() located in src/libproxychains.c. When parsing crafted proxy configuration entries containing overly long username or password fields, the application may write beyond the bounds of fixed-size stack buffers, leading to memory corruption or crashes. This vulnerability may allow denial of service and, under certain conditions, could be leveraged for further exploitation depending on the execution environment and applied mitigations.
