Red Hat Bugzilla – Bug 1005194
su generates incorrect log entries
Last modified: 2015-02-18 06:13:44 EST
Description of problem:
The information logged by su is incorrect. TTY is given as "none" even if there is a tty, and the target user is claimed to be the current user even if that's not the case.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
3. su -c "tail -1 /var/log/messages"
Sep 6 13:59:48 localhost su: (to rtc) rtc on none
Sep 6 13:59:48 localhost su: (to root) rtc on pts/10
su-common.c:log_syslog() calls su-common.c:current_getpwuid() which calls getpwuid(), invalidating the information pointed to by pw in log_syslog(), which has also been obtained by getpwuid(), using a call to su-common.c:current_getpwuid() by su-common.c:authenticate(). See also getpwuid_r(3).
Fixed by upstream commit 9b5dc4cb8d5d82c31c0cda898832998c21afc303.

This message is a notice that Fedora 19 is now at end of life. Fedora
has stopped maintaining and issuing updates for Fedora 19. It is
Fedora's policy to close all bug reports from releases that are no

plan to fix it in a currently maintained version, simply change the 'version'

Thank you for reporting this issue and we are sorry that we were not

of Fedora, you are encouraged change the 'version' to a later Fedora
version prior this bug is closed as described in the policy above.
Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.
Fedora 19 changed to end-of-life (EOL) status on 2015-01-06. Fedora 19 is

Fedora please feel free to reopen this bug against that version. If you
are unable to reopen this bug, please file a new report against the
