The release of this advisory provides exploitation details in relation a weakness in the Linux ASLR implementation. The problem appears when the executable is PIE compiled and it has an address leak belonging to the executable. These details were obtained through the Packet Storm Bug Bounty program and are being released to the community.

af29e970411b02a4faa3410f217a6f31cf2be6b21d710ee65c2ff859aa9a0426This Metasploit module exploits a vulnerability on Microsoft Silverlight. The vulnerability exists on the Initialize() method from System.Windows.Browser.ScriptObject, which access memory in an unsafe manner. Since it is accessible for untrusted code (user controlled) it's possible to dereference arbitrary memory which easily leverages to arbitrary code execution. In order to bypass DEP/ASLR a second vulnerability is used, in the public WriteableBitmap class from System.Windows.dll. This Metasploit module has been tested successfully on IE6 - IE10, Windows XP SP3 / Windows 7 SP1 on both x32 and x64 architectures.
3905f49c6a63195a8b150b72b89466bf89d932607328806dbfade7ebf03e25ceMicrosoft Silverlight 5 suffers from invalid typecast and memory disclosure vulnerabilities that, when leveraged together, allow for arbitrary code execution. A memory disclosure vulnerability exists in the public WriteableBitmap class from System.Windows.dll. This class allows reading of image pixels from the user-defined data stream via the public SetSource() method. BitmapSource.ReadStream() allocates and returns byte array and a count of array items as out parameters. These returned values are taken from the input stream and they can be fully controlled by the untrusted code. When returned "count" is greater than "array.Length", then data outside the "array" are used as input stream data by the native BitmapSource_SetSource() from agcore.dll. Later all data can be viewed via the public WriteableBitmap.Pixels[] property. Exploitation details related to these findings were purchased through the Packet Storm Bug Bounty program.
3bb4d92511f689e34dee499a420b6463240d5b229dbaa5033abb953fb0ba3421This exploit leverages both invalid typecast and memory disclosure vulnerabilities in Microsoft Silverlight 5 in order to achieve code execution. This exploit code demonstrates remote code execution by popping calc.exe. It was obtained through the Packet Storm Bug Bounty program.

52cb4ddd1cdf46517f03dc3f821a50041e929ed003d1d7575ad883ef43571280The ShortComponentRaster.verify() method in Oracle Java versions prior to 7u25 is vulnerable to a memory corruption vulnerability that allows bypassing of "dataOffsets[]" boundary checks when the "numDataElements" field is 0. This vulnerability allows for remote code execution. User interaction is required for this exploit in that the target must visit a malicious page or open a malicious file. This finding was purchased through the Packet Storm Bug Bounty program.

b69d9577ff19470b3048d950dd9549dc3b2aa75f7581440fc3a967b43221d8d6A heap memory buffer overflow vulnerability exists within the WebKit's JavaScriptCore JSArray::sort(...) method. This method accepts the user-defined JavaScript function and calls it from the native code to compare array items. If this compare function reduces array length, then the trailing array items will be written outside the "m_storage->m_vector[]" buffer, which leads to the heap memory corruption. This finding was purchased through the Packet Storm Bug Bounty program.
84bd76ba4dce1e485a3431a2c7bbd07c262e86f184ca05e0931fac224f9ab746A heap memory buffer overflow vulnerability exists within the WebKit's JavaScriptCore JSArray::sort(...) method. The exploit for this vulnerability is javascript code which shows how to use it for memory corruption of internal JS objects (Unit32Array and etc.) and subsequent arbitrary code execution (custom ARM/x64 payloads can be pasted into the JS code). This exploit affects Apple Safari version 6.0.1 for iOS 6.0 and OS X 10.7/8. Earlier versions may also be affected. It was obtained through the Packet Storm Bug Bounty program.

5646d8519790eceedb69ee095dc2f1fc17b73ac3ec0fd514b7fa68ad513dd937Adobe ColdFusion versions 9.0, 9.0.1, and 9.0.2 do not properly check the "rdsPasswordAllowed" field when accessing the Administrator API CFC that is used for logging in. The login function never checks if RDS is enabled when rdsPasswordAllowed="true". This means that if RDS was not configured, the RDS user does not have a password associated with their username. This means by setting rdsPasswordAllowed to "true", we can bypass the admin login to use the rdsPassword, which in most cases, is blank. These details were purchased through the Packet Storm Bug Bounty program and are being released to the community.
