Description:
Updated tomcat6 packages fix security vulnerabilities:
Multiple flaws were found in the way Tomcat handled HTTP DIGEST
authentication. These flaws weakened the Tomcat HTTP DIGEST authentication
implementation, subjecting it to some of the weaknesses of HTTP BASIC
authentication, for example, allowing remote attackers to perform session
replay attacks (CVE-2011-1184, CVE-2011-5062, CVE-2011-5063, CVE-2011-5064).
A flaw was found in the Tomcat MemoryUserDatabase. If a runtime exception
occurred when creating a new user with a JMX client, that user's password
was logged to Tomcat log files. Note: By default, only administrators have
access to such log files (CVE-2011-2204).
A flaw was found in the way Tomcat handled sendfile request attributes when
using the HTTP APR or NIO (Non-Blocking I/O) connector. A malicious web
application running on a Tomcat instance could use this flaw to bypass
security manager restrictions and gain access to files it would otherwise
be unable to access, or possibly terminate the Java Virtual Machine (JVM).
The HTTP blocking IO (BIO) connector, which is not vulnerable to this
issue, is used by default in Red Hat Enterprise Linux 6 (CVE-2011-2526).
It was discovered that Tomcat incorrectly performed certain caching and
recycling operations. A remote attacker could use this flaw to obtain read
access to IP address and HTTP header information in certain cases. This
issue only applied to Ubuntu 11.10 (CVE-2011-3375).
A flaw was found in the way the Coyote (org.apache.coyote.ajp.AjpProcessor)
and APR (org.apache.coyote.ajp.AjpAprProcessor) Tomcat AJP (Apache JServ
Protocol) connectors processed certain POST requests. An attacker could
send a specially-crafted request that would cause the connector to treat
the message body as a new request. This allows arbitrary AJP messages to be
injected, possibly allowing an attacker to bypass a web application's
authentication checks and gain access to information they would otherwise
be unable to access. The JK (org.apache.jk.server.JkCoyoteHandler)
connector is used by default when the APR libraries are not present. The JK
connector is not affected by this flaw (CVE-2011-3190).
It was discovered that Tomcat computed hash values for form parameters
without restricting the ability to trigger hash collisions predictably.
A remote attacker could cause a denial of service by sending many crafted
parameters (CVE-2011-4858).
It was discovered that Tomcat incorrectly handled parameters. A remote
attacker could cause a denial of service by sending requests with a large
number of parameters and values (CVE-2012-0022).
Additionally, errors caused by incorrect permissions on the
/usr/share/tomcat6/work directory have been fixed.
