Vulnerability from fkie_nvd - Published: 2012-02-10 19:55 - Updated: 2025-04-11 00:51
Severity ?
Summary
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.
