Multiple security issues were discovered in Pillow, a Python imaging library, which could result in denial of service and potentially the execution of arbitrary code if malformed PCX, FLI, SGI or TIFF images are processed.
For the oldstable distribution (stretch), these problems have been fixed in version 4.0.0-4+deb9u1.
For the stable distribution (buster), these problems have been fixed in version 5.4.1-2+deb10u1.
We recommend that you upgrade your pillow packages.
