Stack-based buffer overflow vulnerability exists in Linux Ratfor 1.06 and earlier. When the software processes a file which is specially crafted by an attacker, arbitrary code may be executed. As a result, the attacker may obtain or alter information of the user environment or cause the user environment to become unusable.
A stack-based buffer overflow condition is a condition where the buffer being overwritten is allocated on the stack (i.e., is a local variable or, rarely, a parameter to a function).
