Synopsis

The remote Oracle Linux host is missing one or more security updates.

Description

The remote Oracle Linux 6 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2011-1749 advisory.

 - libxml2 before 2.7.8, as used in Google Chrome before 7.0.517.44, Apple Safari 5.0.2 and earlier, and other products, reads from invalid memory locations during processing of malformed XPath expressions, which allows context-dependent attackers to cause a denial of service (application crash) via a crafted XML document. (CVE-2010-4008)

 - Double free vulnerability in libxml2 2.7.8 and other versions, as used in Google Chrome before 8.0.552.215 and other products, allows remote attackers to cause a denial of service or possibly have unspecified other impact via vectors related to XPath handling. (CVE-2010-4494)

 - 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.
 (CVE-2011-0216)

 - Integer overflow in xpath.c in libxml2 2.6.x through 2.6.32 and 2.7.x through 2.7.8, and libxml 1.8.16 and earlier, allows context-dependent attackers to cause a denial of service (crash) and possibly execute arbitrary code via a crafted XML file that triggers a heap-based buffer overflow when adding a new namespace node, related to handling of XPath expressions. (CVE-2011-1944)

 - Double free vulnerability in libxml2, as used in Google Chrome before 13.0.782.215, allows remote attackers to cause a denial of service or possibly have unspecified other impact via a crafted XPath expression. (CVE-2011-2821)

 - Double free vulnerability in libxml2, as used in Google Chrome before 14.0.835.163, allows remote attackers to cause a denial of service or possibly have unspecified other impact via vectors related to XPath handling. (CVE-2011-2834)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected packages.
