high Nessus Plugin ID 145048

Synopsis

The remote Ubuntu host is missing one or more security updates.

Description

The remote Ubuntu 16.04 LTS / 18.04 LTS / 20.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-4697-1 advisory.

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)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
