Summary
pillow vulnerabilities
Details

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. (CVE-2020-35653)

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. (CVE-2020-35654)

It was discovered that Pillow incorrectly handled certain SGI image files. If a user or automated system were tricked into opening a specially-crafted SGI file, a remote attacker could possibly cause Pillow to crash, resulting in a denial of service. This issue only affected Ubuntu 18.04 LTS, Ubuntu 20.04 LTS, and Ubuntu 20.10. (CVE-2020-35655)
