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
