CVE-2015-7500

TITLE

libxml2 Buffer error vulnerability

DESCRIPTION

The xmlParseMisc function in parser.c in libxml2 before 2.9.3 allows context-dependent attackers to cause a denial of service (out-of-bounds heap read) via unspecified vectors related to incorrect entities boundaries and start tags. libxml2 is prone to a denial-of-service vulnerability. Attackers can exploit this issue to cause a denial-of-service condition, denying service to legitimate users. libxml2 2.9.2 is vulnerable; other versions may also be affected. It supports multiple encoding formats, XPath analysis, Well-formed and valid verification, etc. Alternatively, you may manually check for software updates by selecting "Settings -> System -> Software Update -> Update Software.". To check the current version of software, select "Settings -> General -> About". CVE-ID CVE-2016-1722 : Joshua J. For the oldstable distribution (wheezy), these problems have been fixed in version 2.8.0+dfsg1-7+wheezy5. For the stable distribution (jessie), these problems have been fixed in version 2.9.1+dfsg1-5+deb8u1. For the testing distribution (stretch), these problems have been fixed in version 2.9.3+dfsg1-1 or earlier versions. For the unstable distribution (sid), these problems have been fixed in version 2.9.3+dfsg1-1 or earlier versions. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ===================================================================== Red Hat Security Advisory Synopsis: Moderate: libxml2 security update Advisory ID: RHSA-2015:2550-01 Product: Red Hat Enterprise Linux Advisory URL: https://rhn.redhat.com/errata/RHSA-2015-2550.html Issue date: 2015-12-07 CVE Names: CVE-2015-1819 CVE-2015-5312 CVE-2015-7497 CVE-2015-7498 CVE-2015-7499 CVE-2015-7500 CVE-2015-7941 CVE-2015-7942 CVE-2015-8241 CVE-2015-8242 CVE-2015-8317 ===================================================================== 1.

Description: The libxml2 library is a development toolbox providing the implementation of various XML standards. Several denial of service flaws were found in libxml2, a library providing support for reading, modifying, and writing XML and HTML files. A remote attacker could provide a specially crafted XML or HTML file that, when processed by an application using libxml2, would cause that application to use an excessive amount of CPU, leak potentially sensitive information, or in certain cases crash the application.
