CONECTIVA LINUX SECURITY ANNOUNCEMENT 
- --------------------------------------------------------------------------

PACKAGE   : bugzilla
SUMMARY   : Cross site scripting and temporary file vulnerabilities
DATE      : 2003-05-21 17:04:00
ID        : CLA-2003:653

RELEASES  : 9

DESCRIPTION
 Bugzilla[1] is a bug tracking system used by many software projects.
 
 This update fixes the following problems with the bugzilla package
 shipped with Conectiva Linux 9:
 
 1. New dependencies
 The bugzilla package provided via this update has the following new
 dependencies:
 - perl-doc[3];
 - perl-timedate >= 1.14: bugzilla needs a newer version[4] of the
 perl-timedate package than the one shipped with Conectiva Linux 9.
 
 2. Cross site scripting vulnerabilities[2]
 Cross site scripting vulnerabilities have been found in the template
 system and in the dependency graphs which show dependency
 relationships between bugs (not enabled by default). These have been
 fixed in bugzilla 2.16.3.
 
 3. Temporary file vulnerability[2]
 Several scripts create insecure temporary files. A local attacker
 could attempt, with the privileges of the "www" user and via symlink
 attacks, to overwrite or alter files in the system. This
 vulnerability has also been fixed in bugzilla 2.16.3.


SOLUTION
 It is recommended that all bugzilla users upgrade their packages.
 
 IMPORTANT: after the upgrade, please run the following bugzilla
 script:
 
 /srv/www/default/html/bugzilla/checksetup.pl
 
 This script will make all necessary adjustments for this upgrade as
 well as alert about possible problems.
 
 NOTE: since this update introduces two new dependencies to the
 bugzilla packge (perl-doc and perl-timedate >= 1.14), we recommend
 the following command to install the new versions of these packages:
 
 apt-get install bugzilla
 
 Otherwise, if perl-doc or perl-timedate >= 1.14 are not installed,
 "apt-get upgrade" will not upgrade bugzilla.
