Security Advisory squid security update

Advisory: RHSA-2002:130-13
Type: Security Advisory
Severity: Important
Issued on: 2002-06-26
Last updated on: 2002-07-09
Affected Products: Red Hat Enterprise Linux AS (v. 2.1)
CVEs (cve.mitre.org): CVE-2002-0713
CVE-2002-0714
CVE-2002-0715

Details

New Squid packages are available which fix various issues.

Squid is a high-performance proxy caching server. The following summary
describes the various issues found and fixed:

Several buffer overflows have been found in the MSTN auth helper
(msnt_auth) when configured to use denyusers or allowusers access control
files.

Several buffer overflows were found in the gopher client of Squid. It
could be possible for a malicious gopher server to cause Squid to crash.

A problem was found in the handling of the FTP data channel, possibly
allowing abuse of the FTP proxy to bypass firewall rules or inject false
FTP replies.

Several possible buffer overflows were found in the code parsing FTP
directories, which potentially allow for an untrusted FTP server to crash
Squid.

Thanks go to Olaf Kirch and the Squid team for notifying us of the
problems and to the Squid team for providing patches.

All users of Squid are advised to upgrade to these errata packages which
contain patches to correct each of these issues.
