Fix for CVE-2008-5515, CVE-2009-0033, CVE-2009-0580, CVE-2009-0781, and CVE-2009-0783.

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Updated tomcat packages that fix several security issues are now available for Red Hat Network Satellite Server 5.2 and 5.3.

This update has been rated as having low security impact by the Red Hat Security Response Team.

Apache Tomcat is a servlet container for the Java Servlet and JavaServer Pages (JSP) technologies.

This update corrects several security vulnerabilities in the Tomcat component shipped as part of Red Hat Network Satellite Server. In a typical operating environment, Tomcat is not exposed to users of Satellite Server in a vulnerable manner: By default, only Satellite Server applications are running on Tomcat. This update will reduce risk in unique Satellite Server environments.

It was discovered that the Red Hat Security Advisory RHSA-2007:1069 did not address all possible flaws in the way Tomcat handles certain characters and character sequences in cookie values. A remote attacker could use this flaw to obtain sensitive information, such as session IDs, and then use this information for session hijacking attacks.
(CVE-2007-5333)

Note: The fix for the CVE-2007-5333 flaw changes the default cookie processing behavior: With this update, version 0 cookies that contain values that must be quoted to be valid are automatically changed to version 1 cookies. To reactivate the previous, but insecure behavior, add the following entry to the '/etc/tomcat5/catalina.properties' file :

org.apache.tomcat.util.http.ServerCookie.VERSION_SWITCH=false

It was discovered that request dispatchers did not properly normalize user requests that have trailing query strings, allowing remote attackers to send specially crafted requests that would cause an information leak. (CVE-2008-5515)

A flaw was found in the way the Tomcat AJP (Apache JServ Protocol) connector processes AJP connections. An attacker could use this flaw to send specially crafted requests that would cause a temporary denial of service. (CVE-2009-0033)

It was discovered that the error checking methods of certain authentication classes did not have sufficient error checking, allowing remote attackers to enumerate (via brute-force methods) usernames registered with applications running on Tomcat when FORM-based authentication was used. (CVE-2009-0580)

It was discovered that web applications containing their own XML parsers could replace the XML parser Tomcat uses to parse configuration files. A malicious web application running on a Tomcat instance could read or, potentially, modify the configuration and XML-based data of other web applications deployed on the same Tomcat instance. (CVE-2009-0783)

Users of Red Hat Network Satellite Server 5.2 and 5.3 are advised to upgrade to these updated tomcat packages, which contain backported patches to resolve these issues. Tomcat must be restarted for this update to take effect.

An updated tomcat package that fixes several security issues is now available for Red Hat Network Satellite Server 5.1.

This update has been rated as having low security impact by the Red Hat Security Response Team.

Users of Red Hat Network Satellite Server 5.1 are advised to upgrade to this updated tomcat package, which contains backported patches to resolve these issues. Tomcat must be restarted for this update to take effect.

According to its self-reported version number, the Apache Tomcat server listening on the remote host is prior to 4.1.40, 5.5.28, or 6.0.20. It is, therefore, affected by the following vulnerabilities :

  - The remote server is affected by a directory traversal     vulnerability if a RequestDispatcher obtained from a     Request object is used. A specially crafted value for a     request parameter can be used to access potentially     sensitive configuration files or other files, e.g.,     files in the WEB-INF directory. (CVE-2008-5515)

  - The remote server is affected by a denial of service     vulnerability if configured to use the Java AJP     connector. An attacker can send a malicious request with     invalid headers which causes the AJP connector to be put     into an error state for a short time. This behavior can     be used as a denial of service attack. (CVE-2009-0033)

  - The remote server is affected by a username enumeration     vulnerability if configured to use FORM authentication     along with the 'MemoryRealm', 'DataSourceRealm', or     'JDBCRealm' authentication realms. (CVE-2009-0580)

  - The remote server is affected by a script injection     vulnerability if the example JSP application,     'cal2.jsp', is installed. An unauthenticated, remote     attacker can exploit this issue to inject arbitrary HTML     or script code into a user's browser to be executed     within the security context of the affected site.
    (CVE-2009-0781)

  - The remote server is vulnerable to unauthorized     modification of 'web.xml', 'context.xml', or TLD files     of arbitrary web applications. This vulnerability allows     the XML parser, used to process the XML and TLD files,     to be replaced. (CVE-2009-0783)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

 f. Updated Service Console package python

  Service Console package Python update to version 2.4.3-24.el5.

  When the assert() system call was disabled, an input sanitization   flaw was revealed in the Python string object implementation that   led to a buffer overflow. The missing check for negative size values   meant the Python memory allocator could allocate less memory than   expected. This could result in arbitrary code execution with the   Python interpreter's privileges.

  Multiple buffer and integer overflow flaws were found in the Python   Unicode string processing and in the Python Unicode and string   object implementations. An attacker could use these flaws to cause   a denial of service.

  Multiple integer overflow flaws were found in the Python imageop   module. If a Python application used the imageop module to   process untrusted images, it could cause the application to   disclose sensitive information, crash or, potentially, execute   arbitrary code with the Python interpreter's privileges.

  Multiple integer underflow and overflow flaws were found in the   Python snprintf() wrapper implementation. An attacker could use   these flaws to cause a denial of service (memory corruption).

  Multiple integer overflow flaws were found in various Python   modules. An attacker could use these flaws to cause a denial of   service.

  An integer signedness error, leading to a buffer overflow, was   found in the Python zlib extension module. If a Python application   requested the negative byte count be flushed for a decompression   stream, it could cause the application to crash or, potentially,   execute arbitrary code with the Python interpreter's privileges.

  A flaw was discovered in the strxfrm() function of the Python   locale module. Strings generated by this function were not properly   NULL-terminated, which could possibly cause disclosure of data   stored in the memory of a Python application using this function.

  The Common Vulnerabilities and Exposures project (cve.mitre.org)   has assigned the names CVE-2007-2052 CVE-2007-4965 CVE-2008-1721   CVE-2008-1887 CVE-2008-2315 CVE-2008-3142 CVE-2008-3143   CVE-2008-3144 CVE-2008-4864 CVE-2008-5031 to these issues.

 g. Updated Service Console package bind

  Service Console package bind updated to version 9.3.6-4.P1.el5

  The Berkeley Internet Name Domain (BIND) is an implementation of the   Domain Name System (DNS) protocols. BIND includes a DNS server   (named); a resolver library (routines for applications to use when   interfacing with DNS); and tools for verifying that the DNS server   is operating correctly.

  A flaw was found in the way BIND handles dynamic update message   packets containing the 'ANY' record type. A remote attacker could   use this flaw to send a specially crafted dynamic update packet   that could cause named to exit with an assertion failure.

  The Common Vulnerabilities and Exposures project (cve.mitre.org)   has assigned the name CVE-2009-0696 to this issue.

 h. Updated Service Console package libxml2

  Service Console package libxml2 updated to version 2.6.26-2.1.2.8.

  libxml is a library for parsing and manipulating XML files. A   Document Type Definition (DTD) defines the legal syntax (and also   which elements can be used) for certain types of files, such as XML   files.

  A stack overflow flaw was found in the way libxml processes the   root XML document element definition in a DTD. A remote attacker   could provide a specially crafted XML file, which once opened by a   local, unsuspecting user, would lead to denial of service.

  Multiple use-after-free flaws were found in the way libxml parses   the Notation and Enumeration attribute types. A remote attacker   could provide a specially crafted XML file, which once opened by a   local, unsuspecting user, would lead to denial of service.

  The Common Vulnerabilities and Exposures project (cve.mitre.org)   has assigned the names CVE-2009-2414 and CVE-2009-2416 to these   issues.

 i. Updated Service Console package curl

  Service Console package curl updated to version 7.15.5-2.1.el5_3.5

  A cURL is affected by the previously published 'null prefix attack',   caused by incorrect handling of NULL characters in X.509   certificates. If an attacker is able to get a carefully-crafted   certificate signed by a trusted Certificate Authority, the attacker   could use the certificate during a man-in-the-middle attack and   potentially confuse cURL into accepting it by mistake.

  The Common Vulnerabilities and Exposures project (cve.mitre.org)   has assigned the name CVE-2009-2417 to this issue

 j. Updated Service Console package gnutls

  Service Console package gnutil updated to version 1.4.1-3.el5_3.5

  A flaw was discovered in the way GnuTLS handles NULL characters in   certain fields of X.509 certificates. If an attacker is able to get   a carefully-crafted certificate signed by a Certificate Authority   trusted by an application using GnuTLS, the attacker could use the   certificate during a man-in-the-middle attack and potentially   confuse the application into accepting it by mistake.

  The Common Vulnerabilities and Exposures project (cve.mitre.org)   has assigned the name CVE-2009-2730 to this issue
