solutions Security update for squid23 SuSE Linux Maintenance Web (9671ef81a64fa34ac400dd4d33e4256e)

Applies to

Product(s): SuSE Linux Enterprise Server for S/390

Package: squid23
Release: 20020812
Obsoletes: none

Indications

This update should be installed.

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 issue that is not directly squid security related is that squid reliably denies transfer-encoding to work around a recent apache bug. The security fix

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 squid version. See http://www.squid-cache.org/Versions/v2/2.4/bugs/ for more information.

There is a new configuration tag, ftp_sanitycheck. It is on 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.

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 -Fvh squid23.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 in the update.
