Description

Fix stack-based buffer overflow flaw in rlm_pap module: long password hashes used by the PAP module can cause a buffer overflow which may terminate the server.

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
