A flaw was found in the way sealert wrote diagnostic messages to a
temporary file. A local unprivileged user could perform a symbolic
link attack, and cause arbitrary files, writable by other users, to be
overwritten when a victim runs sealert. (CVE-2007-5495)
A flaw was found in the way sealert displayed records from the
setroubleshoot database as unescaped HTML. An local unprivileged
attacker could cause AVC denial events with carefully crafted process
or file names, injecting arbitrary HTML tags into the logs, which
could be used as a scripting attack, or to confuse the user running
Additionally, the following bugs have been fixed in these update
- in certain situations, the sealert process used
excessive CPU. These alerts are now capped at a maximum
of 30, D-Bus is used instead of polling, threads causing
excessive wake-up have been removed, and more robust
exception-handling has been added.
- different combinations of the sealert '-a', '-l', '-H',
and '-v' options did not work as documented.
- the SETroubleShoot browser did not allow multiple
entries to be deleted.
- the SETroubleShoot browser did not display statements
that displayed whether SELinux was using Enforcing or
Permissive mode, particularly when warning about SELinux
- in certain cases, the SETroubleShoot browser gave
incorrect instructions regarding paths, and would not
display the full paths to files.
- adding an email recipient to the recipients option from
the /etc/setroubleshoot/setroubleshoot.cfg file and then
generating an SELinux denial caused a traceback error.
The recipients option has been removed
are now managed through the SETroubleShoot browser by
navigating to File -> Edit Email Alert List, or by
- the setroubleshoot browser incorrectly displayed a
period between the httpd_sys_content_t context and the
- on the PowerPC architecture, The get_credentials()
function in access_control.py would generate an
exception when it called the socket.getsockopt()
- The code which handles path information has been
completely rewritten so that assumptions on path
information which were misleading are no longer made. If
the path information is not present, it will be
presented as '<Unknown>'.
- setroubleshoot had problems with non-English locales
under certain circumstances, possibly causing a python
traceback, an sealert window pop-up containing an error,
a 'RuntimeError: maximum recursion depth exceeded' error
after a traceback, or a 'UnicodeEncodeError' after a
- sealert ran even when SELinux was disabled, causing
'attempt to open server connection failed' errors.
Sealert now checks whether SELinux is enabled or
- the database setroubleshoot maintains was
world-readable. The setroubleshoot database is now mode
600, and is owned by the root user and group.
- setroubleshoot did not validate requests to set AVC
filtering options for users. In these updated packages,
checks ensure that requests originate from the filter
- the previous setroubleshoot packages required a number
of GNOME packages and libraries. setroubleshoot has
therefore been split into 2 packages: setroubleshoot and
- a bug in decoding the audit field caused an 'Input is
not proper UTF-8, indicate encoding!' error message. The
decoding code has been rewritten.
- a file name mismatch in the setroubleshoot init script
would cause a failure to shut down.
