Description

Multiple vulnerabilities has been discovered and corrected in libxml2 :

Off-by-one error in libxml allows remote attackers to execute arbitrary code or cause a denial of service (heap-based buffer overflow and application crash) via a crafted website CVE-2011-0216).

libxml2 allows remote attackers to cause a denial of service (out-of-bounds read) via unspecified vectors (CVE-2011-3905).

The updated packages have been patched to correct these issues.
