Conectiva Linux Advisory: bugzilla

May 22, 2003, 05:29 (0 Talkback[s])
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
RELEVANT
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.
