Debian: DSA-4404-1 Critical: Chromium Use-After-Free Code Execution

Clement Lecigne discovered a use-after-free issue in chromium's file
reader implementation. A maliciously crafted file could be used to
remotely execute arbitrary code because of this problem.

This update also fixes a regression introduced in a previous update. The
browser would always crash when launched in remote debugging mode.

For the stable distribution (stretch), this problem has been fixed in
version 72.0.3626.122-1~deb9u1.

We recommend that you upgrade your chromium packages.
