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

Ubuntu Security Notice (C) 2004-2013 Canonical, Inc. / NASL script (C) 2006-2013 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.

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)
