Debian DLA-529-1 : tomcat7 security update

High Nessus Plugin ID 91835

New! Vulnerability Priority Rating (VPR)

Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.

VPR Score: 4.4

Synopsis

The remote Debian host is missing a security update.

Description

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.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Upgrade the affected packages.
