Description

This security bulletin contains information about 8 secuirty vulnerabilities.


1) Double Free (CVE-ID: CVE-2011-2821)

The vulnerability allows a remote non-authenticated attacker to read and manipulate data.

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.


2) Use-after-free (CVE-ID: CVE-2011-2823)

The vulnerability allows a remote attacker to compromise vulnerable system.

The vulnerability exists due to a use-after-free error when processing vectors involving a line box. A remote attackers can cause a denial of service or possibly have unspecified other impact.

Successful exploitation of the vulnerability may allow an attacker to compromise vulnerable system.


3) Use-after-free (CVE-ID: CVE-2011-2824)
