Red Hat Security Advisory 2013-0266-01 - Apache Tomcat is a servlet container. It was found that sending a request without a session identifier to a protected resource could bypass the Cross-Site Request Forgery prevention filter. A remote attacker could use this flaw to perform CSRF attacks against applications that rely on the CSRF prevention filter and do not contain internal mitigation for CSRF. A flaw was found in the way Tomcat handled sendfile operations when using the HTTP NIO connector and HTTPS. A remote attacker could use this flaw to cause a denial of service. The HTTP NIO connector is used by default in JBoss Enterprise Web Server. The Apache Portable Runtime connector from the Tomcat Native library was not affected by this flaw.

Ubuntu Security Notice 1637-1 - It was discovered that the Apache Tomcat HTTP NIO connector incorrectly handled header data. A remote attacker could cause a denial of service by sending requests with a large amount of header data. It was discovered that Apache Tomcat incorrectly handled DIGEST authentication. A remote attacker could possibly use these flaws to perform a replay attack and bypass authentication. Various other issues were also addressed.

Apache Tomcat suffers from a denial of service vulnerability. The checks that limited the permitted size of request headers were implemented too late in the request parsing process for the HTTP NIO connector. This enabled a malicious user to trigger an OutOfMemoryError by sending a single request with very large headers. Tomcat versions 6.0.0 through 6.0.34 and 7.0.0 through 7.0.27 are affected.
