Bug Fix Advisory

Topic

An updated logwatch package that fixes several bugs is now available for Red Hat
Enterprise Linux 6.

Description

Logwatch is a customizable, pluggable log-monitoring system. It will go through
the user's logs for a given period of time and make a report in the areas that
the user needs.

This update fixes the following bugs:

• Previously, logwatch did not correctly parse the up2date service's
  "updateLoginInfo() login info" messages and displayed them as unmatched entries.
  With this update, parsing of such log messages has been fixed and works as
  expected. (BZ#737247)
  
• Prior to this update, logwatch did not correctly parse many Openswan log
  messages and displayed them as unmatched entries. With this update, parsing of
  such log messages has been fixed and works as expected. (BZ#799690)
  
• Logwatch did not parse Dovecot 2.x log messages properly. That resulted in a
  lot of unmatched entries in its reports. This patch adds additional logic to
  correctly parse Dovecot 2.x logs, thus unmatched entries related to Dovecot 2.x
  messages no longer appear. (BZ#799987)
  
• The .hdr files are headers for RPM packages; they are essentially metadata.
  Logwatch's HTTP service parser emitted warnings for the .hdr files, even when
  the "Detail" parameter was set to "Low". With this update, the .hdr files are
  now parsed as archives, which removes spurious warnings about the .hdr files.
  (BZ#800843)
  
• Previously, logwatch did not correctly handle the "MailTo" option in its
  configuration. That resulted in no output, even though a report should have been
  displayed. This patch adds additional logic to correctly handle an empty
  "MailTo" option. As a result, output is correctly produced even when this option
  is empty. (BZ#837034)
  
• Prior to this update, logwatch did not correctly parse many smartd log
  messages and displayed them as unmatched entries. With this update, parsing of
  such log messages has been fixed and works as expected. (BZ#888007)
  
• Prior to this update, logwatch did not correctly parse DNS log messages with
  DNSSEC validation enabled and displayed them as unmatched entries. With this
  update, parsing of such log messages has been fixed and works as expected.
  (BZ#894134)
  
• Previously, logwatch did not correctly parse the postfix service's "improper
  command pipelining" messages and displayed them as unmatched entries. With this
  update, parsing of such log messages has been fixed and works as expected.
  (BZ#894185)
  
• Previously, logwatch did not correctly parse user names in the secure log. It
  improperly assumed that such names are composed of letters only and displayed
  messages containing names with other symbols, such as digits, as unmatched
  entries. With this update, parsing of user names has been enhanced to include
  underscores and digits, thus log messages containing such user names no longer
  display as unmatched entries. (BZ#894191)
  
• Logins initiated with the "su -" or "su -l" command were not correctly parsed
  by logwatch and were displayed as unmatched entries. This update fixes this bug.
  (BZ#974042)
  
• Prior to this update, logwatch did not correctly parse the RSYSLOG_FileFormat
  time stamps and displayed them as unmatched entries. With this update, parsing
  of the rsyslog time stamps has been fixed and works as expected. (BZ#974044)
  
• SSH Kerberos (GSS) logins were not correctly parsed by logwatch and were
  displayed as unmatched entries. This update fixes this bug. (BZ#974046)
  
• Xen virtual console logins were not correctly parsed by logwatch and were
  displayed as unmatched entries. This update fixes this bug. (BZ#974047)
  

Users of logwatch are advised to upgrade to this updated package, which fixes
these bugs.
