It was found that Subversion's moddavsvn Apache HTTPD server module will use excessive amounts of memory when a large number of properties are set or deleted on a node. This can lead to a DoS.

Setting or deleting a large number of properties on a node (file or directory) will result in a large amount of memory use. Due to the memory pooling behavior of Apache httpd and Subversion the completion of the request will not result in the immediate release of memory used. Repeated commits with the same properties will result in each httpd process plateauing out at some amount of memory. This could result in a Denial of Service if the system is exhausted of all available memory.

Unspecified vulnerability in the VirtualBox component in Oracle Virtualization 4.0, 4.1, and 4.2 allows local users to affect integrity and availability via unknown vectors related to Core. NOTE: The previous information was obtained from the January 2013 Oracle CPU. Oracle has not commented on claims from another vendor that this issue is related to an incorrect comparison in the vgadrawtext function in Devices/Graphics/DevVGA.cpp, which can cause VirtualBox to "draw more lines than necessary."

epan/dissectors/packet-nfs.c in the NFS dissector in Wireshark 1.4.x before 1.4.14, 1.6.x before 1.6.9, and 1.8.x before 1.8.1 allows remote attackers to cause a denial of service (loop and CPU consumption) via a crafted packet.
