Contraindications

None.

Problem description

This package containes fixes for several security issues:
  • Buffer overflows in the gopher client
  • Missing sanity checks of the FTP data channel
  • FTP directory parsing buffer overflows
  • Insecure forwarding of proxy_auth credentials
Another change fixes Squid to reliably drop requests that are using transfer-enconding to work around a recent Apache bug. This is not directly related to Squid security.
  • Buffer overflows in the MSNT auth helper (updating the module from 1.2 to 2.0)
is not included because the module is not activated in this version of Squid.
Please refer to http://www.squid-cache.org/Versions/v2/2.4/bugs/ for more information.

Solution

Please install the updates provided at the location noted below.

Installation notes

This update is provided as an RPM package that can easily be installed onto a running system by using this command:
rpm -Uvh squid.rpm
After the update, a running squid daemon should be restarted using the command
rcsquid restart
The configuration file /etc/squid.conf will not be replaced by the update.
There is a new configuration tag, "ftp_sanitycheck". It is enabled by default and disallows FTP connections to servers using another IP address for the data connection. You can switch it off if you need that feature. Check /etc/squid.conf.rpmnew for details.
