Description

MAWK 1.3.3-17 and prior contains a stack-based buffer overflow vulnerability that allows attackers to execute arbitrary code by exploiting inadequate boundary checks on user-supplied input. Attackers can craft malicious input that overflows the stack buffer and execute a return-oriented programming chain to spawn a shell with application privileges.
