Descriptions
In Pillow before 8.1.0, PcxDecode has a buffer over-read when decoding a crafted PCX file because the user-supplied stride value is trusted for buffer calculations.

A flaw was found in python-pillow. The PcxDecode in Pillow has a buffer over-read when decoding a crafted PCX file due to the user-supplied stride value trusted for buffer calculations. The highest threat from this vulnerability is to system availability.
It was discovered that Pillow incorrectly handled certain PCX image files. If a user or automated system were tricked into opening a specially-crafted PCX file, a remote attacker could possibly cause Pillow to crash, resulting in a denial of service. It was discovered that Pillow incorrectly handled certain Tiff image files. If a user or automated system were tricked into opening a specially-crafted Tiff file, a remote attacker could cause Pillow to crash, resulting in a denial of service, or possibly execute arbitrary code. This issue only affected Ubuntu 20.04 LTS and Ubuntu 20.10. Various other issues were also addressed.
