Description

It was discovered that there were three vulnerabilities in Pillow, an imaging library for the Python programming language :

  • CVE-2019-19911: Prevent a denial of service vulnerability caused by FpxImagePlugin.py calling the range function on an unvalidated 32-bit integer if the number of bands is large.

  • CVE-2020-5312: PCX 'P mode' buffer overflow.

  • CVE-2020-5313: FLI buffer overflow.

For Debian 8 'Jessie', these issues have been fixed in pillow version 2.6.1-2+deb8u4.

We recommend that you upgrade your pillow packages.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
