CVE-2012-0839

Publication date 8 February 2012

Last updated 24 July 2024

Ubuntu priority

Low

Why this priority?

OCaml 3.12.1 and earlier 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.

New randomization turned off by default and must be specifically turned on by application. See upstream bug report. Downgrading severity to low, since upstream won't change default behaviour.
