CVE-2012-5373 (GCVE-0-2012-5373)

Vulnerability from cvelistv5 – Published: 2012-11-28 11:00 – Updated: 2024-08-06 21:05
VLAI
Summary
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.
