Hehe. We are not using bzip2 so it doesn't affect us. But I'll update to 1.4.1 anyway. Best Regards, /Andreas 2012-05-23 16:49, Vincent Massol skrev:

From: Stefan Bodewig <[email protected]> Subject: [CVE-2012-2098] Apache Commons Compress and Apache Ant denial of service vulnerability Date: May 23, 2012 4:00:48 PM GMT+02:00 To: [email protected], [email protected], [email protected], [email protected], [email protected], [email protected], [email protected], [email protected], David Jorm <[email protected]>

CVE-2012-2098: Apache Commons Compress and Apache Ant denial of service vulnerability

Severity: Low

Vendor: The Apache Software Foundation

Versions Affected: Apache Commons Compress 1.0 to 1.4 Apache Ant 1.5 to 1.8.3

Description: The bzip2 compressing streams in Apache Commons Compress and Apache Ant internally use sorting algorithms with unacceptable worst-case performance on very repetitive inputs. A specially crafted input to Compress' BZip2CompressorOutputStream or Ant's <bzip2> task can be used to make the process spend a very long time while using up all available processing time effectively leading to a denial of service.

Mitigation: Commons Compress users should upgrade to 1.4.1 Ant users should upgrade to 1.8.4

Credit: This issue was discovered by David Jorm of the Red Hat Security Response Team.
