TITLE

Apple Safari Used in products such as libxml Vulnerable to one-off error

DESCRIPTION

Off-by-one error in libxml in Apple Safari before 5.0.6 allows remote attackers to execute arbitrary code or cause a denial of service (heap-based buffer overflow and application crash) via a crafted web site. Windows Run on Apple Safari of libxml There is one gap (Off-by-one) An error vulnerability exists. This vulnerability libxml Vulnerability. Apple Safari is prone to a remote code-execution vulnerability. Attackers may exploit this issue to execute arbitrary code in the context of the application. Failed exploit attempts will crash the application. This issue affects Apple Safari versions prior to 5.1 and 5.0.6. NOTE: This issue was previously discussed in BID 48808 (Apple Safari Prior to 5.1 and 5.0.6 Multiple Security Vulnerabilities) but has been given its own record to better document it. Apple Apple Safari is a web browser developed by Apple (Apple), and is the default browser included with Mac OS X and iOS operating systems. 6) - i386, x86_64 3. (CVE-2010-4008, CVE-2010-4494, CVE-2011-2821, CVE-2011-2834) Note: Red Hat does not ship any applications that use libxml2 in a way that would allow the CVE-2011-1944, CVE-2010-4008, CVE-2010-4494, CVE-2011-2821, and CVE-2011-2834 flaws to be exploited; however, third-party applications may allow XPath expressions to be passed which could trigger these flaws. This update also fixes the following bugs: * A number of patches have been applied to harden the XPath processing code in libxml2, such as fixing memory leaks, rounding errors, XPath numbers evaluations, and a potential error in encoding conversion. The desktop must be restarted (log out, then log back in) for this update to take effect. CVE-2011-2821: A memory corruption (double free) bug has been identified in libxml2's XPath engine. Through it, it is possible to an attacker allows cause a denial of service or possibly have unspecified other impact. This vulnerability does not affect the oldstable distribution (lenny). CVE-2011-2834: Yang Dingning discovered a double free vulnerability related to XPath handling. CVE-2011-3905: An out-of-bounds read vulnerability had been discovered, which allows remote attackers to cause a denial of service.

This issue is addressed by removing DigiNotar from the list of trusted root certificates, from the list of Extended Validation (EV) certificate authorities, and by configuring default system trust settings so that DigiNotar's certificates, including those issued by other authorities, are not trusted. Apple TV Available for: Apple TV 4.0 through 4.3 Impact: Support for X.509 certificates with MD5 hashes may expose users to spoofing and information disclosure as attacks improve Description: Certificates signed using the MD5 hash algorithm were accepted by iOS. This algorithm has known cryptographic weaknesses. Further research or a misconfigured certificate authority could have allowed the creation of X.509 certificates with attacker controlled values that would have been trusted by the system. This would have exposed X.509 based protocols to spoofing, man in the middle attacks, and information disclosure. This update disables support for an X.509 certificate with an MD5 hash for any use other than as a trusted root certificate. CVE-ID CVE-2011-3427 Apple TV Available for: Apple TV 4.0 through 4.3 Impact: An attacker could decrypt part of a SSL connection Description: Only the SSLv3 and TLS 1.0 versions of SSL were supported. A man-in-the-middle attacker could have injected invalid data, causing the connection to close but revealing some information about the previous data. If the same connection was attempted repeatedly the attacker may eventually have been able to decrypt the data being sent, such as a password. This issue is addressed by adding support for TLS 1.2. CVE-ID CVE-2011-0241 : Cyril CATTIAUX of Tessi Technologies Apple TV Available for: Apple TV 4.0 through 4.3 Impact: A remote attacker may cause a device reset Description: The kernel failed to promptly reclaim memory from incomplete TCP connections. An attacker with the ability to connect to a listening service on an iOS device could exhaust system resources. CVE-ID CVE-2011-3259 : Wouter van der Veer of Topicus I&I, and Josh Enders Apple TV Available for: Apple TV 4.0 through 4.3 Impact: An attacker with a privileged network position may cause an unexpected application termination or arbitrary code execution Description: A one-byte heap buffer overflow existed in libxml's handling of XML data. CVE-ID CVE-2011-0216 : Billy Rios of the Google Security Team Apple TV Available for: Apple TV 4.0 through 4.3 Impact: An attacker with a privileged network position may cause an unexpected application termination or arbitrary code execution Description: A memory corruption issue existed in JavaScriptCore. CVE-ID CVE-2011-3232 : Aki Helin of OUSPG Installation note: Apple TV will periodically check for software updates. Alternatively, you may manually check for software updates by selecting "Settings -> General -> Update Software". To check the current version of software, select "Settings -> General -> About". -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ===================================================================== Red Hat Security Advisory Synopsis: Important: mingw32-libxml2 security update Advisory ID: RHSA-2013:0217-01 Product: Red Hat Enterprise Linux Advisory URL: https://rhn.redhat.com/errata/RHSA-2013-0217.html Issue date: 2013-01-31 CVE Names: CVE-2010-4008 CVE-2010-4494 CVE-2011-0216 CVE-2011-1944 CVE-2011-2821 CVE-2011-2834 CVE-2011-3102 CVE-2011-3905 CVE-2011-3919 CVE-2012-0841 CVE-2012-5134 ===================================================================== 1. 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. (CVE-2011-3919) A heap-based buffer underflow flaw was found in the way libxml2 decoded certain entities. (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. (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. (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. (CVE-2011-3905) Red Hat would like to thank the Google Security Team for reporting the CVE-2010-4008 issue. 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.
