   An update that solves three vulnerabilities and has three
   fixes is now available.

Description:

   This update for Tomcat fixes the following security issues:

   - CVE-2014-7810: Security manager bypass via EL expressions. (bsc#931442)
     It was found that the expression language resolver evaluated expressions
     within a privileged code section. A malicious web application could have
     used this flaw to bypass security manager protections.

   - CVE-2014-0227: Limited DoS in chunked transfer encoding input filter.
     (bsc#917127) It was discovered that the ChunkedInputFilter
     implementation did not fail subsequent attempts to read input early
     enough. A remote attacker could have used this flaw to perform a denial
     of service attack, by streaming an unlimited quantity of data, leading
     to consumption of server resources.

   - CVE-2014-0230: Non-persistent DoS attack by feeding data by aborting an
     upload It was possible for a remote attacker to trigger a non-persistent
     DoS attack by feeding data by aborting an upload. (bsc#926762)

   Additionally, the following non-security issues have been fixed:

   - Fix rights of all files within /usr/share/tomcat6/bin. (bsc#906152)
   - Don't overwrite /var/run/tomcat6.pid when Tomcat is already running.
     (bsc#934219)
   - Miscellaneous fixes and improvements to Tomcat's init script.
     (bsc#932698)
