tomcat7 vulnerabilities
============================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 15.04
- Ubuntu 14.10
- Ubuntu 14.04 LTS
Summary:
Several security issues were fixed in Tomcat.
Software Description:
- tomcat7: Servlet and JSP engine
Details:
It was discovered that the Tomcat XML parser incorrectly handled XML
External Entities (XXE). A remote attacker could possibly use this issue to
read arbitrary files. This issue only affected Ubuntu 14.04 LTS.
(CVE-2014-0119)
It was discovered that Tomcat incorrectly handled data with malformed
chunked transfer coding. A remote attacker could possibly use this issue to
conduct HTTP request smuggling attacks, or cause Tomcat to consume
resources, resulting in a denial of service. This issue only affected
Ubuntu 14.04 LTS. (CVE-2014-0227)
It was discovered that Tomcat incorrectly handled HTTP responses occurring
before the entire request body was finished being read. A remote attacker
could possibly use this issue to cause memory consumption, resulting in a
denial of service. This issue only affected Ubuntu 14.04 LTS.
(CVE-2014-0230)
It was discovered that the Tomcat Expression Language (EL) implementation
incorrectly handled accessible interfaces implemented by inaccessible
classes. An attacker could possibly use this issue to bypass a
SecurityManager protection mechanism. (CVE-2014-7810)
Update instructions:
The problem can be corrected by updating your system to the following
package versions:
Ubuntu 15.04:
libtomcat7-java 7.0.56-2ubuntu0.1
Ubuntu 14.10:
libtomcat7-java 7.0.55-1ubuntu0.2
Ubuntu 14.04 LTS:
libtomcat7-java 7.0.52-1ubuntu0.3
In general, a standard system update will make all the necessary changes.
