Ubuntu 4.10 : XML library vulnerabilities (USN-10-1)

Ubuntu Security Notice (C) 2004-2016 Canonical, Inc. / NASL script (C) 2006-2016 Tenable Network Security, Inc.


Synopsis :

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

Description :

Several buffer overflows have been discovered in libxml2's FTP
connection and DNS resolution functions. Supplying very long FTP URLs
or IP addresses might result in execution of arbitrary code with the
privileges of the process using libxml2.

Since libxml2 is used in packages like php4-imagick, the vulnerability
also might lead to privilege escalation, like executing attacker
supplied code with a web server's privileges.

However, this does not affect the core XML parsing code, which is what
the majority of programs use this library for.

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 :

Critical / CVSS Base Score : 10.0
(CVSS2#AV:N/AC:L/Au:N/C:C/I:C/A:C)
