TITLE

Expat of expat/lib/xmlparse.c Service disruption in ( Memory consumption ) Vulnerabilities

DESCRIPTION

Memory leak in the poolGrow function in expat/lib/xmlparse.c in expat before 2.1.0 allows context-dependent attackers to cause a denial of service (memory consumption) via a large number of crafted XML files that cause improperly-handled reallocation failures when expanding entities. The Expat library is prone to multiple denial-of-service vulnerabilities because it fails to properly handle crafted XML data. Exploiting these issues allows remote attackers to cause denial-of-service conditions in the context of an application using the vulnerable XML parsing library. Expat versions prior to 2.1.0 are vulnerable. This update provides the corresponding updates for XML-RPC for C and C++. Both issues described in the original advisory affected XML-RPC for C and C++ in Ubuntu 10.04 LTS, 11.04, 11.10 and 12.04 LTS. This issue only affected Ubuntu 8.04 LTS, 10.04 LTS, 11.04 and 11.10. ============================================================================ Ubuntu Security Notice USN-1613-1 October 17, 2012 python2.5 vulnerabilities ============================================================================ A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 8.04 LTS Summary: Several security issues were fixed in Python 2.5. Software Description: - python2.5: An interactive high-level object-oriented language (version 2.5) Details: It was discovered that Python would prepend an empty string to sys.path under certain circumstances. A local attacker with write access to the current working directory could exploit this to execute arbitrary code. (CVE-2008-5983) It was discovered that the audioop module did not correctly perform input validation. If a user or automatated system were tricked into opening a crafted audio file, an attacker could cause a denial of service via application crash. (CVE-2010-1634, CVE-2010-2089) Giampaolo Rodola discovered several race conditions in the smtpd module. A remote attacker could exploit this to cause a denial of service via daemon outage. (CVE-2010-3493) It was discovered that the CGIHTTPServer module did not properly perform input validation on certain HTTP GET requests. A remote attacker could potentially obtain access to CGI script source files. (CVE-2011-1015) Niels Heinen discovered that the urllib and urllib2 modules would process Location headers that specify a redirection to file: URLs. A remote attacker could exploit this to obtain sensitive information or cause a denial of service. (CVE-2011-1521) It was discovered that SimpleHTTPServer did not use a charset parameter in the Content-Type HTTP header. An attacker could potentially exploit this to conduct cross-site scripting (XSS) attacks against Internet Explorer 7 users. (CVE-2011-4940) It was discovered that Python distutils contained a race condition when creating the ~/.pypirc file. A local attacker could exploit this to obtain sensitive information. (CVE-2011-4944) It was discovered that SimpleXMLRPCServer did not properly validate its input when handling HTTP POST requests. A remote attacker could exploit this to cause a denial of service via excessive CPU utilization. (CVE-2012-0845) It was discovered that the Expat module in Python 2.5 computed hash values without restricting the ability to trigger hash collisions predictably. (CVE-2012-1148) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 8.04 LTS: python2.5 2.5.2-2ubuntu6.2 python2.5-minimal 2.5.2-2ubuntu6.2 In general, a standard system update will make all the necessary changes. - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Gentoo Linux Security Advisory GLSA 201209-06 - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - http://security.gentoo.org/ - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Severity: Normal Title: Expat: Multiple vulnerabilities Date: September 24, 2012 Bugs: #280615, #303727, #407519 ID: 201209-06 - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Synopsis ======== Multiple vulnerabilities have been found in Expat, possibly resulting in Denial of Service.

Description: Expat is a C library written by James Clark for parsing XML documents. A denial of service flaw was found in the implementation of hash arrays in Expat. An attacker could use this flaw to make an application using Expat consume an excessive amount of CPU time by providing a specially-crafted XML file that triggers multiple hash function collisions. To mitigate this issue, randomization has been added to the hash function to reduce the chance of an attacker successfully causing intentional collisions. (CVE-2012-0876) A memory leak flaw was found in Expat. If an XML file processed by an application linked against Expat triggered a memory re-allocation failure, Expat failed to free the previously allocated memory. This could cause the application to exit unexpectedly or crash when all available memory is exhausted. (CVE-2012-1148) All Expat users should upgrade to these updated packages, which contain backported patches to correct these issues. After installing the updated packages, applications using the Expat library must be restarted for the update to take effect. 4. Solution: Before applying this update, make sure all previously-released errata relevant to your system have been applied. This update is available via the Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at https://access.redhat.com/knowledge/articles/11258 5.
