Trustix Secure Linux Security Advisory #2001-0013

Package name:      Squid
Severity:          Allows for unauthorized use of the web proxy
Date:              2001-07-19
Affected versions: TSL 1.01, 1.1, 1.2

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

Problem description:
  From the squid list of changes:
    Versions 2.3.STABLE2 through 2.3.STABLE4 have a serious security bug
    when Squid is used in the 'httpd_accel' mode. If you configured
    httpd_accel_with_proxy off then any request to Squid is allowed.
    Malicious users may use your proxy to port-scan remote systems,
    forge email, and do other nasty things.

  Note that this is not the default configuration on TSL, but we still
  recommend that you update it.

Action:
  We recommend that all systems with this package installed are upgraded.


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


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

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