CVE-2013-3134 is a vulnerability of currently unknown severity. The Common Language Runtime (CLR) in Microsoft .NET Framework 2.0 SP2, 3.5, 3.5.1, 4, and 4.5 on 64-bit platforms does not properly allocate arrays of structures, which allows remote attackers to execute arbitrary code via a crafted .NET Framework application that changes array data, aka "Array Allocation Vulnerability.". EPSS estimates a 21.04% chance of exploitation in the next 30 days.
