Package        : tiff
Version        : 4.0.8-2+deb9u7
CVE ID         : CVE-2020-19131 CVE-2020-19144

Two security issues were found in TIFF, a widely used format for
storing image data, as follows:

CVE-2020-19131

    Buffer Overflow in LibTiff allows attackers to cause
    a denial of service via the "invertImage()" function
    in the component "tiffcrop".

CVE-2020-19144

    Buffer Overflow in LibTiff allows attackers to cause
    a denial of service via the 'in _TIFFmemcpy' funtion
    in the component 'tif_unix.c'.

For Debian 9 stretch, these problems have been fixed in version
4.0.8-2+deb9u7.

We recommend that you upgrade your tiff packages.
