CVE-2012-5372

The vulnerability CVE-2012-5372 affects Rubinius’ MurmurHash3 implementation. The hash function does not adequately restrict the ability to trigger hash collisions, enabling context-dependent attackers to cause high CPU usage and DoS by sending crafted input to an application that uses a hash tab...

CVE-2012-2739

CVE-2012-2739 affects Oracle Java SE prior to 7 Update 6 and OpenJDK 7 prior to 7u6 build 12, and OpenJDK 8 prior to build 39. The vulnerability stems from computing hash values without restricting hash collisions, enabling context-dependent attackers to cause CPU exhaustion (DoS) by crafting inp...
