Freshness: upstream tracker timestamp is available; use API updated time as primary recency signal.
CVE-2012-0840 low priority: Ubuntu including 1 source packages (apr), 13 status rows across 13 suites (hardy, lucid, maverick, natty, oneiric, precise, quantal, raring, saucy, trusty, upstream, utopic, vivid): not-affected 7, ignored 5, released 1.
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.
