CVE-2012-5373

java: Murmur hash function collisions (oCERT-2012-001)

Published Nov 28, 2012 CVSS 2.0 · 5.0 Medium EPSS 2.3% KEV · Not listed
Description
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.
