high Nessus Plugin ID 159631

Language:

Synopsis

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

Description

The remote Ubuntu 18.04 LTS / 20.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-5331-2 advisory.

 - The command-line argument parser in tcpdump before 4.99.0 has a buffer overflow in tcpdump.c:read_infile(). To trigger this vulnerability the attacker needs to create a 4GB file on the local filesystem and to specify the file name as the value of the -F command-line argument of tcpdump.
 (CVE-2018-16301)

 - The ppp decapsulator in tcpdump 4.9.3 can be convinced to allocate a large amount of memory.
 (CVE-2020-8037)

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

Solution

Update the affected tcpdump package.
