DESCRIPTION:
Multiple vulnerabilities have been reported in Google Chrome, where

people to potentially compromise a user's system.

corrupt memory.

2) An unspecified error related to the processing of an enormous text
area can be exploited to corrupt memory.

3) An error related to a bad cast exists within the handling of the
SVG use element.

4) An unspecified error in the XPath handling can be exploited to
access invalid memory. 

5) A use-after-free error related to text control selections can be

These vulnerabilities affect only the Linux platform.

7) An unspecified error in libvpx can be exploited to corrupt
memory.

8) An unspecified error exists related to the usage of a destroyed
frame object.
