    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
      <URI:http://www.trustix.net/pub/Trustix/updates/>
      <URI: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:
      <URI:ftp://ftp.trustix.net/pub/Trustix/software/swup/>
