========================================================================== Ubuntu Security Notice USN-1685-1 January 14, 2013
tomcat6, tomcat7 vulnerabilities ==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 12.10 - Ubuntu 12.04 LTS - Ubuntu 11.10 - Ubuntu 10.04 LTS
Summary:
Several security issues were fixed in Tomcat.
Software Description: - tomcat7: Servlet and JSP engine - tomcat6: Servlet and JSP engine
Details:
It was discovered that Tomcat incorrectly performed certain security constraint checks in the FORM authenticator. A remote attacker could possibly use this flaw with a specially-crafted URI to bypass security constraint checks. This issue only affected Ubuntu 10.04 LTS, Ubuntu 11.10 and Ubuntu 12.04 LTS. (CVE-2012-3546)
It was discovered that Tomcat incorrectly handled requests that lack a session identifier. A remote attacker could possibly use this flaw to bypass the cross-site request forgery protection. (CVE-2012-4431)
It was discovered that Tomcat incorrectly handled sendfile and HTTPS when the NIO connector is used. A remote attacker could use this flaw to cause Tomcat to stop responsing, resulting in a denial of service. This issue only affected Ubuntu 10.04 LTS, Ubuntu 11.10 and Ubuntu 12.04 LTS. (CVE-2012-4534)
Update instructions:
The problem can be corrected by updating your system to the following package versions:
Ubuntu 12.10: libtomcat7-java 7.0.30-0ubuntu1.1
Ubuntu 12.04 LTS: libtomcat6-java 6.0.35-1ubuntu3.2
Ubuntu 11.10: libtomcat6-java 6.0.32-5ubuntu1.4
Ubuntu 10.04 LTS: libtomcat6-java 6.0.24-2ubuntu1.12
In general, a standard system update will make all the necessary changes.
