Ubuntu 6.06 LTS / 6.10 : squid vulnerabilities (USN-414-1)

Ubuntu Security Notice (C) 2007-2016 Canonical, Inc. / NASL script (C) 2007-2016 Tenable Network Security, Inc.


Synopsis :

The remote Ubuntu host is missing one or more security-related
patches.

Description :

David Duncan Ross Palmer and Henrik Nordstrom discovered that squid
incorrectly handled special characters in FTP URLs. Remote users with
access to squid could crash the server leading to a denial of service.
(CVE-2007-0247)

Erick Dantas Rotole and Henrik Nordstrom discovered that squid could
end up in an endless loop when exhausted of available external ACL
helpers. Remote users with access to squid could cause CPU starvation,
possibly leading to a denial of service. This does not affect a
default Ubuntu installation, since external ACL helpers must be
configured and used. (CVE-2007-0248).

Note that Tenable Network Security has extracted the preceding
description block directly from the Ubuntu security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues.

Solution :

Update the affected packages.

Risk factor :

Medium / CVSS Base Score : 5.0
(CVSS2#AV:N/AC:L/Au:N/C:N/I:N/A:P)
CVSS Temporal Score : 4.3
(CVSS2#E:ND/RL:OF/RC:C)
