Discussion

Ruby 'pack.c' Buffer Overflow Vulnerability

Ruby is prone to a buffer overflow vulnerability because it fails to adequate boundary checks on user-supplied input.

An attacker can exploit this issue to execute arbitrary code in the context of the application using the affected function. Failed exploit attempts will likely crash the application.

Ruby 1.9.3 is vulnerable; other versions may also be affected.
