CVE-2012-2733

Publication date 16 November 2012

Last updated 24 July 2024

Ubuntu priority

Medium

Why this priority?

java/org/apache/coyote/http11/InternalNioInputBuffer.java in the HTTP NIO connector in Apache Tomcat 6.x before 6.0.36 and 7.x before 7.0.28 does not properly restrict the request-header size, which allows remote attackers to cause a denial of service (memory consumption) via a large amount of header data.
