Ubuntu Security Notice (C) 2012-2014 Canonical, Inc. / NASL script (C) 2012-2014 Tenable Network Security, Inc.


Synopsis :

The remote Ubuntu host is missing a security-related patch.

Description :

It was discovered that PHP incorrectly handled certain Tidy::diagnose
operations on invalid objects. A remote attacker could use this flaw
to cause PHP to crash, leading to a denial of service. (CVE-2012-0781)

It was discovered that PHP incorrectly handled certain multi-file
upload filenames. A remote attacker could use this flaw to cause a
denial of service, or to perform a directory traversal attack.
(CVE-2012-1172)

Rubin Xu and Joseph Bonneau discovered that PHP incorrectly handled
certain Unicode characters in passwords passed to the crypt()
function. A remote attacker could possibly use this flaw to bypass
authentication. (CVE-2012-2143)

It was discovered that a Debian/Ubuntu specific patch caused PHP to
incorrectly handle empty salt strings. A remote attacker could
possibly use this flaw to bypass authentication. This issue only
affected Ubuntu 10.04 LTS and Ubuntu 11.04. (CVE-2012-2317)

It was discovered that PHP, when used as a stand alone CGI processor
for the Apache Web Server, did not properly parse and filter query
strings. This could allow a remote attacker to execute arbitrary code
running with the privilege of the web server, or to perform a denial
of service. Configurations using mod_php5 and FastCGI were not
vulnerable. (CVE-2012-2335, CVE-2012-2336)

Alexander Gavrun discovered that the PHP Phar extension incorrectly
handled certain malformed TAR files. A remote attacker could use this
flaw to perform a denial of service, or possibly execute arbitrary
code. (CVE-2012-2386).

Solution :

Update the affected php5 package.
