It was discovered that there were three vulnerabilities in Pillow, an imaging library for the Python programming language
There is a DoS vulnerability in Pillow before 6.2.2 caused by FpxImagePlugin.py calling the range function on an unvalidated 32-bit integer if the number of bands is large. On Windows running 32-bit Python, this results in an OverflowError or MemoryError due to the 2 GB limit. However, on Linux running 64-bit Python this results in the process being terminated by the OOM killer.
libImaging/PcxDecode.c in Pillow before 6.2.2 has a PCX P mode buffer overflow.
libImaging/FliDecode.c in Pillow before 6.2.2 has an FLI buffer overflow.
For Debian 8 Jessie
, these problems have been fixed in version
2.6.1-2+deb8u4.
We recommend that you upgrade your pillow packages.
