TITLE

libxml2 Resource Management Error Vulnerability

DESCRIPTION

libxml2 before 2.8.0 computes hash values without restricting the ability to trigger hash collisions predictably, which allows context-dependent attackers to cause a denial of service (CPU consumption) via crafted XML data. libxml2 is prone to a denial-of-service vulnerability. An attacker can exploit this issue by sending specially crafted requests to the affected application that uses a hash table. It supports multiple encoding formats, XPath analysis, Well-formed and valid verification, etc. The vulnerability is caused by the program calculating the hash value without pre-limiting the hash collision. An attacker with a privileged network position may inject arbitrary contents. This issue was addressed by using an encrypted HTTPS connection to retrieve tutorials. ============================================================================ Ubuntu Security Notice USN-1376-1 February 27, 2012 libxml2 vulnerability ============================================================================ A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 11.10 - Ubuntu 11.04 - Ubuntu 10.10 - Ubuntu 10.04 LTS - Ubuntu 8.04 LTS Summary: libxml2 could be made to cause a denial of service by consuming excessive CPU resources. Software Description: - libxml2: GNOME XML library Details: Juraj Somorovsky discovered that libxml2 was vulnerable to hash table collisions. Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 11.10: libxml2 2.7.8.dfsg-4ubuntu0.2 Ubuntu 11.04: libxml2 2.7.8.dfsg-2ubuntu0.3 Ubuntu 10.10: libxml2 2.7.7.dfsg-4ubuntu0.4 Ubuntu 10.04 LTS: libxml2 2.7.6.dfsg-1ubuntu1.4 Ubuntu 8.04 LTS: libxml2 2.6.31.dfsg-2ubuntu1.8 After a standard system update you need to reboot your computer to make all the necessary changes. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 - ------------------------------------------------------------------------- Debian Security Advisory DSA-2417-1 security@debian.org http://www.debian.org/security/ Nico Golde February 22, 2012 http://www.debian.org/security/faq - ------------------------------------------------------------------------- Package : libxml2 Vulnerability : computational denial of service Problem type : local/remote Debian-specific: no Debug bug : 660846 CVE ID : CVE-2012-0841 It was discovered that the internal hashing routine of libxml2, a library providing an extensive API to handle XML data, is vulnerable to predictable hash collisions. Given an attacker with knowledge of the hashing algorithm, it is possible to craft input that creates a large amount of collisions. As a result it is possible to perform denial of service attacks against applications using libxml2 functionality because of the computational overhead. For the stable distribution (squeeze), this problem has been fixed in version 2.7.8.dfsg-2+squeeze3. For the testing (wheezy) and unstable (sid) distributions, this problem will be fixed soon. We recommend that you upgrade your libxml2 packages. Charter: http://lists.grok.org.uk/full-disclosure-charter.html Hosted and sponsored by Secunia - http://secunia.com/ .

Summary: Updated mingw32-libxml2 packages that fix several security issues are now available for Red Hat Enterprise Linux 6. This advisory also contains information about future updates for the mingw32 packages, as well as the deprecation of the packages with the release of Red Hat Enterprise Linux 6.4. The Red Hat Security Response Team has rated this update as having important security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section. 2. Relevant releases/architectures: Red Hat Enterprise Linux Desktop Optional (v. 6) - noarch Red Hat Enterprise Linux HPC Node Optional (v. 6) - noarch Red Hat Enterprise Linux Server Optional (v. 6) - noarch Red Hat Enterprise Linux Workstation Optional (v. 6) - noarch 3. Description: These packages provide the libxml2 library, a development toolbox providing the implementation of various XML standards, for users of MinGW (Minimalist GNU for Windows). IMPORTANT NOTE: The mingw32 packages in Red Hat Enterprise Linux 6 will no longer be updated proactively and will be deprecated with the release of Red Hat Enterprise Linux 6.4. These packages were provided to support other capabilities in Red Hat Enterprise Linux and were not intended for direct customer use. Customers are advised to not use these packages with immediate effect. Future updates to these packages will be at Red Hat's discretion and these packages may be removed in a future minor release. A heap-based buffer overflow flaw was found in the way libxml2 decoded entity references with long names. A remote attacker could provide a specially-crafted XML file that, when opened in an application linked against libxml2, would cause the application to crash or, potentially, execute arbitrary code with the privileges of the user running the application. (CVE-2011-3919) A heap-based buffer underflow flaw was found in the way libxml2 decoded certain entities. A remote attacker could provide a specially-crafted XML file that, when opened in an application linked against libxml2, would cause the application to crash or, potentially, execute arbitrary code with the privileges of the user running the application. (CVE-2012-5134) It was found that the hashing routine used by libxml2 arrays was susceptible to predictable hash collisions. Sending a specially-crafted message to an XML service could result in longer processing time, which could lead to a denial of service. To mitigate this issue, randomization has been added to the hashing function to reduce the chance of an attacker successfully causing intentional collisions. (CVE-2012-0841) Multiple flaws were found in the way libxml2 parsed certain XPath (XML Path Language) expressions. If an attacker were able to supply a specially-crafted XML file to an application using libxml2, as well as an XPath expression for that application to run against the crafted file, it could cause the application to crash. (CVE-2010-4008, CVE-2010-4494, CVE-2011-2821, CVE-2011-2834) Two heap-based buffer overflow flaws were found in the way libxml2 decoded certain XML files. A remote attacker could provide a specially-crafted XML file that, when opened in an application linked against libxml2, would cause the application to crash or, potentially, execute arbitrary code with the privileges of the user running the application. (CVE-2011-0216, CVE-2011-3102) An integer overflow flaw, leading to a heap-based buffer overflow, was found in the way libxml2 parsed certain XPath expressions. If an attacker were able to supply a specially-crafted XML file to an application using libxml2, as well as an XPath expression for that application to run against the crafted file, it could cause the application to crash or, possibly, execute arbitrary code. (CVE-2011-1944) An out-of-bounds memory read flaw was found in libxml2. A remote attacker could provide a specially-crafted XML file that, when opened in an application linked against libxml2, would cause the application to crash. Upstream acknowledges Bui Quang Minh from Bkis as the original reporter of CVE-2010-4008. All users of mingw32-libxml2 are advised to upgrade to these updated packages, which contain backported patches to correct these issues. 4. This update is available via the Red Hat Network.
