Amazon Linux AMI : libxml2 (ALAS-2012-134)

Medium Nessus Plugin ID 69624

Synopsis

The remote Amazon Linux AMI host is missing a security update.

Description

Multiple integer overflow flaws, leading to heap-based buffer overflows, were found in the way libxml2 handled documents that enable entity expansion. A remote attacker could provide a large, specially crafted XML file that, when opened in an application linked against libxml2, would cause the application to crash or, potentially, execute arbitrary code with the privileges of the user running the application. (CVE-2012-2807)

A one byte buffer overflow was found in the way libxml2 evaluated certain parts of XML Pointer Language (XPointer) expressions. A remote attacker could provide a specially crafted XML file that, when opened in an application linked against libxml2, would cause the application to crash or, potentially, execute arbitrary code with the privileges of the user running the application. (CVE-2011-3102)

Solution

Run 'yum update libxml2' to update your system.
