   An update that fixes four vulnerabilities is now available.

Description:


   This update fixes a regression in parameter passing (in
   urldecoding of  parameters that contain spaces).

   In addition, multiple weaknesses in HTTP DIGESTS have been
   fixed  (CVE-2011-1184):

   * CVE-2011-5062: The HTTP Digest Access Authentication
   implementation in Apache Tomcat 5.5.x before 5.5.34, 6.x
   before 6.0.33 and 7.x before 7.0.12 does not check qop
   values, which might allow remote attackers to bypass
   intended integrity-protection requirements via a qop=auth
   value, a different vulnerability than CVE-2011-1184.
   * CVE-2011-5063: The HTTP Digest Access Authentication
   implementation in Apache Tomcat 5.5.x before 5.5.34, 6.x
   before 6.0.33, and 7.x before 7.0.12 does not check realm
   values, which might allow remote attackers to bypass
   intended access restrictions by leveraging the availability
   of a protection space with weaker authentication or
   authorization requirements, a different vulnerability than
   CVE-2011-1184.
   * CVE-2011-5064: DigestAuthenticator.java in the HTTP
   Digest Access Authentication implementation in Apache
   Tomcat 5.5.x before 5.5.34, 6.x before 6.0.33, and 7.x
   before 7.0.12 uses Catalina as the hard-coded server secret
   (aka private key), which makes it easier for remote
   attackers to bypass cryptographic protection mechanisms by
   leveraging knowledge of this string, a different
   vulnerability than CVE-2011-1184.
