CVE-2014-2015: Buffer Overflow

First published: Wed Feb 19 2014(Updated: )

Pierre Carrier reported a stack-based buffer overflow flaw in the FreeRADIUS rlm_pap module. An authenticated user could trigger this issue by creating a large password, causing FreeRADIUS to crash. The stack protector and SSP variable re-ordering protections should help prevent this issue from being used to execute arbitrary code.
