Message-Id: <02AC8AFB-A0BF-4916-9F2B-CCA5009FB81C@apache.org> Date: Wed, 31 Mar 2010 15:48:01 +0200 From: Jan Lehnardt <jan@...che.org> To: dev@...chdb.apache.org Cc: user@...chdb.apache.org, security@...chdb.apache.org, Jason Davies <jasondavies@...che.org>, full-disclosure@...ts.grok.org.uk, bugtraq@...urityfocus.com, security@...che.org Subject: [SECURITY] CVE-2008-2370: Apache CouchDB Timing Attack Vulnerability CVE-2008-2370: Apache CouchDB Timing Attack Vulnerability Severity: Important Vendor: The Apache Software Foundation Versions Affected: Apache CouchDB 0.8.0 to 0.10.1 Description: Apache CouchDB versions prior to version 0.11.0 are vulnerable to timing attacks, also known as side-channel information leakage, due to using simple break-on-inequality string comparisons when verifying hashes and passwords. Mitigation: All users should upgrade to CouchDB 0.11.0. Upgrades from the 0.10.x series should be seamless. Users on earlier versions should consult http://wiki.apache.org/couchdb/Breaking_changes Example: A canonical description of the attack can be found in http://codahale.com/a-lesson-in-timing-attacks/ Credit: This issue was discovered by Jason Davies of the Apache CouchDB development team.
