What is CVE-2012-5373?
CVE-2012-5373 is a medium-severity denial of service vulnerability in Oracle Jdk, published on 28 Nov 2012. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official 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.
Weakness: CWE-310
Which versions are affected by CVE-2012-5373?
It affects 3 products.
Products include Oracle Jdk, Oracle Jre, Oracle Openjdk.
