CVE-2012-4557

Publication date 30 November 2012

Last updated 24 July 2024

Ubuntu priority

Low

Why this priority?

The mod_proxy_ajp module in the Apache HTTP Server 2.2.12 through 2.2.21 places a worker node into an error state upon detection of a long request-processing time, which allows remote attackers to cause a denial of service (worker consumption) via an expensive request.
