Debian DLA-1276-1 : tomcat-native security update

medium Nessus Plugin ID 106724

Synopsis

The remote Debian host is missing a security update.

Description

Jonas Klempel discovered that, when parsing the AIA-Extension field of a client certificate, Apache Tomcat Native did not correctly handle fields longer than 127 bytes. The result of the parsing error was to skip the OCSP check. It was therefore possible for client certificates that should have been rejected (if the OCSP check had been made) to be accepted. Users not using OCSP checks are not affected by this vulnerability.

For Debian 7 'Wheezy', these problems have been fixed in version 1.1.24-1+deb7u1.

We recommend that you upgrade your tomcat-native 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 libtcnative-1 package.
