  script_tag(name:"insight", value:"A denial of service vulnerability was identified in Commons FileUpload that occurred when the length of the multipart boundary was just below the size of the buffer (4096 bytes) used to read the uploaded file. This caused the file upload process to take several orders of magnitude longer than if the boundary was the typical tens of bytes long.

Apache Tomcat uses a package renamed copy of Apache Commons FileUpload to implement the file upload requirements of the Servlet specification and was therefore also vulnerable to the denial of service vulnerability.

For Debian 7 Wheezy, these problems have been fixed in version 7.0.28-4+deb7u5.

We recommend that you upgrade your tomcat7 packages.
