Drupal core’s Image module allows for the on-demand generation of image derivatives. This capability can be abused by requesting a large number of new derivatives which can fill up the server disk space, and which can cause a very high CPU load. Either of these effects may lead to the site becoming unavailable or unresponsive.
Please see the Drupal 7.20 release notes for important notes about the changes which were made to fix this issue, since some sites will require extra testing and care when deploying this Drupal core release.
Race condition in win32k.sys in the kernel-mode drivers in Microsoft Windows XP SP2 and SP3, Windows Server 2003 SP2, Windows Vista SP2, Windows Server 2008 SP2, R2, and R2 SP1, Windows 7 Gold and SP1, Windows 8, Windows Server 2012, and Windows RT allows local users to gain privileges, and consequently read the contents of arbitrary kernel memory locations, via a crafted application, a different vulnerability than other CVEs listed in MS13-016.
Microsoft Internet Explorer 6 through 9 does not properly perform auto-selection of the Shift JIS encoding, which allows remote attackers to read content from a different (1) domain or (2) zone via a crafted web site that triggers cross-domain scrolling events, aka “Shift JIS Character Encoding Vulnerability.”
Use-after-free vulnerability in Microsoft Internet Explorer 6 through 10 allows remote attackers to execute arbitrary code via a crafted web site that triggers access to a deleted object, aka “Internet Explorer vtable Use After Free Vulnerability.”
The Windows Forms (aka WinForms) component in Microsoft .NET Framework 2.0 SP2, 3.5, 3.5.1, 4, and 4.5 does not properly restrict the privileges of a callback function during object creation, which allows remote attackers to execute arbitrary code via (1) a crafted XAML browser application (XBAP) or (2) a crafted .NET Framework application, aka “WinForms Callback Elevation Vulnerability.”
plugins/system/highlight/highlight.php in Joomla! 3.0.x through 3.0.2 and 2.5.x through 2.5.8 allows attackers to unserialize arbitrary PHP objects to obtain sensitive information, delete arbitrary directories, conduct SQL injection attacks, and possibly have other impacts via the highlight parameter. Note: it was originally reported that this issue only allowed attackers to obtain sensitive information, but later analysis demonstrated that other attacks exist. (CVSS:5.0) (Last Update:2013-03-06)
Joomla! 3.0.x through 3.0.2 allows attackers to obtain sensitive information via unspecified vectors related to “Coding errors.” (CVSS:5.0) (Last Update:2013-03-26)
Joomla! 3.0.x through 3.0.2 allows attackers to obtain sensitive information via unspecified vectors related to an “Undefined variable.” (CVSS:5.0) (Last Update:2013-02-13)
