Trustix Secure Linux Security Advisory #2002-0040

Package name:      zlib and derived packages
Summary:           double free() vulerability
Date:              2002-03-18
Affected versions: TSL 1.01, 1.1, 1.2, 1.5

- --------------------------------------------------------------------------

Problem description:
  zlib version 1.1.3 and lower contains a vulnerability which, in a worst case
  scenario, might allow an attacker to execute arbitary code. This problem is 
  solved by upgrading to the new release of zlib.
  
  All programs which are dynamicly linked with this library needs to be 
  restarted after the zlib upgrade. This include, among others: openssh and 
  postgresql. To ensure that these services are in fact restarted, the TSL-team
  have upgraded them aswell. 
  Users of the swup software update tool will benefit greatly from this.
  
  Some programs are staticly linked with this library and have been 
  recomplied using the new release of zlib as part of the build environment. 
  
  Also some programs have parts of the zlib source code copied into their own 
  source code, and may therefore be vulnerable. These will be updated when 
  analysis tells us that they are in fact vulnerable.

  Following is a list of the updated packages:
  - zlib (Upgrade: 1.1.4-1tr)
  - openssh (Rebuild: 3.1.0p1-2tr)
  - postgresql (Rebuild: 7.1.2-4tr)
  - mysql (Rebuild: 3.23.47-2tr)
  - rpm (Rebuild: 3.0.6-7tr)
  - rsync (Upgrade: 2.5.4-1tr)
  - kernel (Patch: 2.2.20-2tr)
  - sash (Upgrade: 3.5-1tr)
  - ppp (Ugrade/patch: 2.4.1-1tr)

  We have also included some of the updates that have been in the public
  testing directories for a while:

  1.5: man and procmail
  1.2: apache apache-ssl

Action:
  We recommend that all systems with this package installed are upgraded.
  Please note that if you do not need the functionality provided by some of 
  these packages, you may want to remove them from your system.


Location:
  All TSL updates are available from
  <URI:http://www.trustix.net/pub/Trustix/updates/>

Automatic updates:
  Users of the SWUP tool can enjoy having updates automatically
  installed using 'swup --upgrade'.

  Get SWUP from:
  <URI:ftp://ftp.trustix.net/pub/Trustix/software/swup/>


Public testing:
  These packages have been available for public testing for some time.
  If you want to contribute by testing the various packages in the
  testing tree, please feel free to share your findings on the
  tsl-discuss mailinglist.
