Debian Security Advisory DSA 2399-2 (php5)

CVE Author: NIST National Vulnerability Database
CVSS Base Vector:
AV:N/AC:L/Au:N/C:P/I:P/A:P
Technical Details:
A regression was found in the fix for PHP's XSLT transformations
(CVE-2012-0057). Updated Linux Distribution Packages are now available to address this
regression. For reference, the original advisory text follows.
Several vulnerabilities have been discovered in PHP, the web scripting
language. The Common Vulnerabilities and Exposures project identifies
the following issues:
CVE-2011-1938
The UNIX socket handling allowed attackers to trigger a buffer overflow
via a long path name.
CVE-2011-2483
The crypt_blowfish function did not properly handle 8-bit characters,
which made it easier for attackers to determine a cleartext password
by using knowledge of a password hash.
CVE-2011-4566
When used on 32 bit platforms, the exif extension could be used to
trigger an integer overflow in the exif_process_IFD_TAG function
when processing a JPEG file.
CVE-2011-4885
It was possible to trigger hash collisions predictably when parsing
form parameters, which allows remote attackers to cause a denial of
service by sending many crafted parameters.
CVE-2012-0057
When applying a crafted XSLT transform, an attacker could write files
to arbitrary places in the filesystem.
NOTE: the fix for CVE-2011-2483 required changing the behaviour of this
function: it is now incompatible with some old (wrongly) generated hashes
for passwords containing 8-bit characters. See the Linux Distribution Package NEWS entry
for details. This change has not been applied to the Lenny version of PHP.
NOTE: at the time of release Linux Distribution Packages for some architectures are still
being built. They will be installed into the archive as soon as they
arrive.
For the oldstable distribution (lenny), these problems have been fixed
in version 5.2.6.dfsg.1-1+lenny15.
For the stable distribution (squeeze), these problems have been fixed
in version 5.3.3-7+squeeze6.
For the testing distribution (wheezy) and unstable distribution (sid),
these problems have been fixed in version 5.3.9-1.
Recommendations:
We recommend that you upgrade your php5 Linux Distribution Packages.
Summary:
The remote host is missing an update to php5
announced via advisory DSA 2399-2.

Free Vulnerability Scanning, Assessment and Management
Mageni's Platform is packed with all the features you need to scan, assess and manage vulnerabilities like this - it is free, open source, lightning fast, reliable and scalable.
Frequently Asked Questions
Do you limit the number of concurrent scans?
No, you can scan concurrently as many assets as you want. Please note that you must be aware of the hardware requeriments of the platform to ensure a good performance.
Do you limit the number of assets?
No, you can add as many assest as you want. It doesn't matters if you have millions of assets, we won't charge you for that.
Will I ever be charged to use the software?
No. The software is completely free. We have no intention to charge you to use the software, in fact - it completely goes against our beliefs and business model.
What's a vulnerability?
A vulnerability is defined in the ISO 27002 standard as “A weakness of an asset or group of assets that can be exploited by one or more threats” (International Organization for Standardization, 2005)
How can you offer this for free?
We generate revenue by providing support and other services for customers that require a subscription so they get guaranteed support and enterprise services. To use Mageni's Platform is completely free, with no limits at all.

Do you store my vulnerability information on your servers?
No, we don't store the information of your vulnerabilities in our servers.
What's vulnerability management?
Vulnerability management is the process in which vulnerabilities in IT are identified and the risks of these vulnerabilities are evaluated. This evaluation leads to correcting the vulnerabilities and removing the risk or a formal risk acceptance by the management of an organization. The term vulnerability management is often confused with vulnerability scanning. Despite the fact both are related, there is an important difference between the two. Vulnerability scanning consists of using a computer program to identify vulnerabilities in networks, computer infrastructure or applications. Vulnerability management is the process surrounding vulnerability scanning, also taking into account other aspects such as risk acceptance, remediation etc. Source: "Implementing a Vulnerability Management Process".
