Summary

libxml2 2.7.0 and 2.7.1 does not properly handle "predefined entities definitions" in entities, which allows context-dependent attackers to cause a denial of service (memory consumption and application crash), as demonstrated by use of xmllint on a certain XML document, a different vulnerability than CVE-2003-1564 and CVE-2008-3281.

    descriptionThe remote host is affected by the vulnerability described in GLSA-200812-06 (libxml2: Multiple vulnerabilities) Multiple vulnerabilities were reported in libxml2: Andreas Solberg reported that libxml2 does not properly detect recursion during entity expansion in an attribute value (CVE-2008-3281). A heap-based buffer overflow has been reported in the xmlParseAttValueComplex() function in parser.c (CVE-2008-3529). Christian Weiske reported that predefined entity definitions in entities are not properly handled (CVE-2008-4409). Drew Yao of Apple Product Security reported an integer overflow in the xmlBufferResize() function that can lead to an infinite loop (CVE-2008-4225). Drew Yao of Apple Product Security reported an integer overflow in the xmlSAX2Characters() function leading to a memory corruption (CVE-2008-4226). Impact : A remote attacker could entice a user or automated system to open a specially crafted XML document with an application using libxml2, possibly resulting in the exeution of arbitrary code or a high CPU and memory consumption. Workaround : There is no known workaround at this time.
