Last modified

CVE-2012-0840 is a vulnerability of currently unknown severity. tables/apr_hash.c in the Apache Portable Runtime (APR) library through 1.4.5 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.. EPSS estimates a 43.35% chance of exploitation in the next 30 days.
