Adobe Flash Player before 10.2.154.27 on Windows, Mac OS X, Linux, and Solaris and 10.2.156.12 and earlier on Android; Adobe AIR before 2.6.19140; and Authplay.dll (aka AuthPlayLib.bundle) in Adobe Reader 9.x before 9.4.4 and 10.x through 10.0.1 on Windows, Adobe Reader 9.x before 9.4.4 and 10.x before 10.0.3 on Mac OS X, and Adobe Acrobat 9.x before 9.4.4 and 10.x before 10.0.3 on Windows and Mac OS X allow remote attackers to execute arbitrary code or cause a denial of service (application crash) via crafted Flash content; as demonstrated by a Microsoft Office document with an embedded .swf file that has a size inconsistency in a "group of included constants," object type confusion, ActionScript that adds custom functions to prototypes, and Date objects; and as exploited in the wild in April 2011.

Adobe Flash Player contains an unspecified vulnerability that allows remote attackers to execute code or cause denial-of-service (DoS).

Exim 4.72 and earlier allows local users to gain privileges by leveraging the ability of the exim user account to specify an alternate configuration file with a directive that contains arbitrary commands, as demonstrated by the spooldirectory directive.

Double free vulnerability in libxml2 2.7.8 and other versions, as used in Google Chrome before 8.0.552.215 and other products, allows remote attackers to cause a denial of service or possibly have unspecified other impact via vectors related to XPath handling.

Description of problem: On parsing malformed X.25 facilities, decrementing the remaining length may cause it to underflow. Since the length is an unsigned integer, this will result in the loop continuing until the kernel crashes.

This patch adds checks to ensure decrementing the remaining length does not cause it to wrap around.

Statement:

This issue did not affect the versions of Linux kernel as shipped with Red Hat Enterprise Linux 4, 5, 6 and Red Hat Enterprise MRG as they did not include support for CCITT X.25 Packet Layer.

Google Chrome before 7.0.517.41 does not properly handle animated GIF images, which allows remote attackers to cause a denial of service (memory corruption) or possibly have unspecified other impact via a crafted image.

Description of problem: The handling functions for sending and receiving messages, in rdspagecopyuser(), use the unchecked copyuserinatomic functions without any access checks on user-provided pointers. As a result, by passing a kernel address as an iovec base address in recvmsg-style calls, a local user can overwrite arbitrary kernel memory, which can easily be used to escalate privileges to root.

Adobe Flash Player before 9.0.277.0 and 10.x before 10.1.53.64; Adobe AIR before 2.0.2.12610; and Adobe Reader and Acrobat 9.x before 9.3.3, and 8.x before 8.2.3 on Windows and Mac OS X, allow remote attackers to execute arbitrary code or cause a denial of service (memory corruption) via crafted SWF content, related to authplay.dll and the ActionScript Virtual Machine 2 (AVM2) newfunction instruction, as exploited in the wild in June 2010.

Sauli Pahlman of CERT-FI provided us with fuzzed PDF file which causes xpdf / poppler PDF parser to crash.

The crash is caused by an attempt to dereference uninitialized Gfx::parser pointer in Gfx::getPos(), which assumes parser is either NULL or valid Parser pointer.

Use-after-free vulnerability in WebKit in Apple Safari before 4.0.5 allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via an HTML document with improperly nested tags.

Adobe Acrobat and Reader contains an array boundary issue in Universal 3D (U3D) support that could lead to remote code execution.

Common Vulnerabilities and Exposures assigned an identifier CVE-2009-4324 to the following vulnerability:

Name: CVE-2009-4324 URL: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2009-4324 Assigned: 20091214 Reference: MISC: http://blogs.adobe.com/psirt/2009/12/newadobereaderandacrobatv.html

Unspecified vulnerability in Adobe Reader and Acrobat 9.2 and earlier has unknown impact and attack vectors, as exploited in the wild in December 2009.

An unconfirmed third-party posting [1] indicates this vulnerability is in the JavaScript processing, so a proposed work-around is to disable JavaScript (Edit -> Preferences -> JavaScript). This has not been official confirmed by Adobe.

The XSL stylesheet implementation in WebKit in Apple Safari before 4.0, iPhone OS 1.0 through 2.2.1, and iPhone OS for iPod touch 1.1 through 2.2.1 does not properly handle XML external entities, which allows remote attackers to read arbitrary files via a crafted DTD, as demonstrated by a file:///etc/passwd URL in an entity declaration, related to an "XXE attack."
