-Subject: pam_timestamp: fix potential directory traversal issue (ticket #27)
-
-pam_timestamp uses values of PAM_RUSER and PAM_TTY as components of
-the timestamp pathname it creates, so extra care should be taken to
-avoid potential directory traversal issues.
-
-* modules/pam_timestamp/pam_timestamp.c (check_tty): Treat
-"." and ".." tty values as invalid.
-(get_ruser): Treat "." and ".." ruser values, as well as any ruser
-value containing '/', as invalid.
-
-Fixes CVE-2014-2583.
