* pam_timestamp: fix typo in strncmp usageDmitry V. Levin2016-06-14
| | | | | | | | | | | | Before this fix, a typo in check_login_time resulted to ruser and struct utmp.ut_user being compared by the first character only, which in turn could lead to a too low timestamp value being assigned to oldest_login, effectively causing bypass of check_login_time. * modules/pam_timestamp/pam_timestamp.c (check_login_time): Fix typo in strncmp usage.

* Don't use sudo directory, the timestamp format is different (Ticket#32)Thorsten Kukuk2015-03-24

* pam_timestamp: fix potential directory traversal issue (ticket #27)Dmitry V. Levin2014-03-26
| | | | | | | | | | | | | | | 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. Reported-by: Sebastian Krahmer <krahmer@suse.de>
