medium Nessus Plugin ID 177426

Language:

Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 16.04 ESM / 18.04 ESM / 20.04 LTS / 22.04 LTS host has packages installed that are affected by a vulnerability as referenced in the USN-6176-1 advisory.

 It was discovered that PyPDF2 incorrectly handled certain PDF files. If a

 user or automated system were tricked into processing a specially crafted file, an attacker could possibly use this issue to consume system resources, resulting in a denial of service.

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

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