CVE-2012-2739

Publication date 28 November 2012

Last updated 24 July 2024

Description

Oracle Java SE before 7 Update 6, and OpenJDK 7 before 7u6 build 12 and 8 before build 39, computes hash values without 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.

openjdk-6b18 in oneiric has been superceded by openjdk-6 openjdk-6b18 in lucid & natty would be superceded by openjdk-6 except that openjdk-6 FTBFS on armel (LP: #1043003)

this was actually fixed in usn-1619-1 as part of the new upstream releases, but it wasn't reported as such.
