DESCRIPTION:
Multiple vulnerabilities have been reported in Google Chrome, where
some have an unknown impact and others can be exploited by malicious
people to manipulate certain data and potentially compromise a user's
system.

1) An unspecified error exists within the extensions notification
handling.

2) A second unspecified error exists when handling pointers within
node iteration.

3) A third unspecified error exists when printing multi-page PDF
files.

4) An error when handling CSS and canvas can be exploited to
reference a stale pointer.

5) An error when handling CSS and cursors can be exploited to
reference a stale pointer.

6) A use-after-free error when handling PDF pages can be exploited to
reference freed memory.

7) An error due to an out-of-memory condition when processing PDF
files can be exploited to cause stack corruption.

8) An error when handling mismatched video frame sizes can be
exploited to reference invalid memory.

9) An error when handling SVG "<use>" elements can be exploited to
reference a stale pointer.

10) An error when handling rouge extensions can be exploited to
reference an uninitialised pointer.

11) An error within the Vorbis decoder can be exploited to cause a
buffer overflow.

12) An error within PDF shading can be exploited to cause a buffer
overflow.

13) An error when handling anchors may result in an incorrect type
cast.

14) An error when handling videos may result in an incorrect type
cast.

15) An error after removal of a DOM node may result in a stale
rendering node.
