NASL family VMware ESX Local Security Checks NASL id VMWARE_VMSA-2008-0017.NASL description a. Updated ESX Service Console package libxml2 A denial of service flaw was found in the way libxml2 processes certain content. If an application that is linked against libxml2 processes malformed XML content, the XML content might cause the application to stop responding. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2008-3281 to this issue. Additionally the following was also fixed, but was missing in the security advisory. A heap-based buffer overflow flaw was found in the way libxml2 handled long XML entity names. If an application linked against libxml2 processed untrusted malformed XML content, it could cause the application to crash or, possibly, execute arbitrary code. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2008-3529 to this issue. b.

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. last seen 2020-06-01 modified 2020-06-02 plugin id 35023 published 2008-12-03 reporter This script is Copyright (C) 2008-2019 Tenable Network Security, Inc. source https://www.tenable.com/plugins/nessus/35023 title GLSA-200812-06 : libxml2: Multiple vulnerabilities NASL family Oracle Linux Local Security Checks NASL id ORACLELINUX_ELSA-2008-0836.NASL description From Red Hat Security Advisory 2008:0836 : Updated libxml2 packages that fix a security issue are now available.

If an application linked against libxml2 processed untrusted malformed XML content, it could cause the application to crash or possibly execute arbitrary code (CVE-2008-3529). The updated packages have been patched to prevent this issue. As well, the patch to fix CVE-2008-3281 has been updated to remove the hard-coded entity limit that was set to 5M, instead using XML entity density heuristics. Many thanks to Daniel Veillard of Red Hat for his hard work in tracking down and dealing with the edge cases discovered with the initial fix to this issue. last seen 2020-06-01 modified 2020-06-02 plugin id 38013 published 2009-04-23 reporter This script is Copyright (C) 2009-2019 Tenable Network Security, Inc. source https://www.tenable.com/plugins/nessus/38013 title Mandriva Linux Security Advisory : libxml2 (MDVSA-2008:192) NASL family MacOS X Local Security Checks NASL id MACOSX_SAFARI4_0.NASL description The version of Apple Safari installed on the remote Mac OS X host is earlier than 4.0.
