medium Nessus Plugin ID 59238

Synopsis

The remote Ubuntu host is missing one or more security-related patches.

Description

It was discovered that feedparser did not properly sanitize ENTITY declarations in encoded fields. A remote attacker could exploit this to cause a denial of service via memory exhaustion.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected python-feedparser and / or python3-feedparser packages.
