CVE-2012-5373: n/a vulnerability

CVE-2012-5373: Oracle Java SE 7 and earlier, and OpenJDK 7 and earlier, computes hash values without properly restricting...

Oracle Java SE 7 and earlier, and OpenJDK 7 and earlier, computes hash values without properly restricting the ability to trigger hash collisions predictably, which allows context-dependent attackers to cause a denial of service (CPU consumption) via crafted input to an application that maintains a hash table, as demonstrated by a universal multicollision attack against the MurmurHash3 algorithm, a different vulnerability than CVE-2012-2739.

Security readout for executives and security teams

This is an availability risk in older Java/OpenJDK runtimes. Crafted input can make applications spend excessive CPU processing hash-table data, potentially slowing or denying service. The record provides no CVSS score, named patch, or confirmed active exploitation. Exposure is most likely in legacy Java/OpenJDK 7-or-earlier applications that accept attacker-controlled input later stored or processed in hash tables. Internet-facing request parsers and APIs may carry higher availability risk. Treat as a targeted availability concern for legacy Java estates, not an emergency without exposure. Prioritize internet-facing or revenue-critical services still on Java/OpenJDK 7 or earlier. Mitigation focus: Inventory applications running Java SE 7 or earlier or OpenJDK 7 or earlier.; Check Oracle, OpenJDK, distribution, or application vendor guidance for supported remediation.; Prioritize replacing unsupported legacy Java runtimes where business-critical services are exposed..
