Synopsis :

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

Description :

It was discovered that an integer overflow in the XML UTF-8 decoding

protections. This issue only affected Ubuntu 6.06 LTS, Ubuntu 8.04
LTS, and Ubuntu 9.10. (CVE-2009-5016)

It was discovered that the XML UTF-8 decoding code did not properly
handle non-shortest form UTF-8 encoding and ill-formed subsequences in
UTF-8 data, which could allow an attacker to bypass cross-site
scripting (XSS) protections. (CVE-2010-3870)

It was discovered that attackers might be able to bypass
open_basedir() restrictions by passing a specially crafted filename.
(CVE-2010-3436)

Maksymilian Arciemowicz discovered that a NULL pointer derefence in
the ZIP archive handling code could allow an attacker to cause a
denial of service through a specially crafted ZIP archive. This issue
only affected Ubuntu 8.04 LTS, Ubuntu 9.10, Ubuntu 10.04 LTS, and
Ubuntu 10.10. (CVE-2010-3709)

It was discovered that a stack consumption vulnerability in the
filter_var() PHP function when in FILTER_VALIDATE_EMAIL mode, could
allow a remote attacker to cause a denial of service. This issue only
affected Ubuntu 8.04 LTS, Ubuntu 9.10, Ubuntu 10.04 LTS, and Ubuntu
10.10. (CVE-2010-3710)

It was discovered that the mb_strcut function in the Libmbfl library
within PHP could allow an attacker to read arbitrary memory within the
application process. This issue only affected Ubuntu 10.10.
(CVE-2010-4156)

Maksymilian Arciemowicz discovered that an integer overflow in the
NumberFormatter::getSymbol function could allow an attacker to cause a

Ubuntu 10.10. (CVE-2010-4409)

Rick Regan discovered that when handing PHP textual representations of
the largest subnormal double-precision floating-point number, the
zend_strtod function could go into an infinite loop on 32bit x86
processors, allowing an attacker to cause a denial of service.
(CVE-2010-4645).

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.
