Debian: DSA-4870-1 Critical: tiff DoS and Remote Code Execution

Two vulnerabilities have been discovered in the libtiff library
and the included tools, which may result in denial of service or the
execution of arbitrary code if malformed image files are processed.

For the stable distribution (buster), these problems have been fixed in
version 4.1.0+git191117-2~deb10u2.

We recommend that you upgrade your tiff packages.
