Ubuntu 22.04 LTS : less vulnerability (USN-5848-1)

high Nessus Plugin ID 171211

Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 22.04 LTS host has a package installed that is affected by a vulnerability as referenced in the USN-5848-1 advisory.

David Leadbeater discovered that less was not properly handling escape sequences when displaying raw control characters. A maliciously formed OSC 8 hyperlink could possibly be used by an attacker to cause 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.

Solution

Update the affected less package.
