Apache Tomcat < 6.0.32 / 7.0.8 NIO Connector DoS

Medium Nessus Plugin ID 51987

Synopsis

The remote web server is affected by a denial of service vulnerability.

Description

According to its self-reported version number, the instance of Apache Tomcat listening on the remote host is prior to 6.0.32 or 7.0.8. It is, therefore, affected by a denial of service vulnerability. An error, involving the NIO HTTP connector, exists such that the limit 'maxHttpHeaderSize' is not enforced thereby allowing a denial of service condition when memory is exhausted.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update Apache Tomcat to version 6.0.32 / 7.0.8 or later.
