DESCRIPTION:
Multiple vulnerabilities have been reported in Google Chrome, which
can be exploited by malicious people to conduct spoofing attacks,
disclose potentially sensitive information, and compromise a user's
system.

1) An error within regex matching can be exploited to cause an
out-of-bounds read.

2) An error in libxml can be exploited to cause an out-of-bounds
read.

3) An error in the PDF parser can be exploited to cause an
out-of-bounds read.

4) An error in the view-source functionality can be exploited to
spoof a URL bar.

5) An error within SVG parsing can be exploited to cause an
out-of-bounds read.

6) An error when handling a CSS property array can be exploited to
corrupt memory.

NOTE: This vulnerability affects the 64-bit platforms only.

7) An error when handling YUV video frames can be exploited to cause
an out-of-bounds read.

8) An error within PDF handling can be exploited to cause an
out-of-bounds read.

9) A use-after-free error exists in SVG filters.

10) A use-after-free error exists within Range handling.

11) An error within v8 i18n handling can be exploited to cause an
out-of-bounds write.

12) An error when handling certain PDF fonts can be exploited to
cause a buffer overflow.

13) An error when handling PDF cross references can be exploited to
cause an out-of-bounds read.

14) An error in FileWatcher can be exploited to cause a stack-based
buffer overflow.

15) A use-after-free error exists within bidi handling.

Successful exploitation of vulnerabilities #6, #9 - #12, #14, and #15
may allow execution of arbitrary code.

SOLUTION:
Upgrade to version 16.0.912.63.
