Amazon Linux 2 : ipmitool (ALAS-2020-1420)

high Nessus Plugin ID 136363

Language:

Synopsis

The remote Amazon Linux 2 host is missing a security update.

Description

The version of ipmitool installed on the remote host is prior to 1.8.18-9. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2020-1420 advisory.

 It's been found that multiple functions in ipmitool before 1.8.19 neglect proper checking of the data received from a remote LAN party, which may lead to buffer overflows and potentially to remote code execution on the ipmitool side. This is especially dangerous if ipmitool is run as a privileged user. This problem is fixed in version 1.8.19. (CVE-2020-5208)

Tenable has extracted the preceding description block directly from the tested product 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

Run 'yum update ipmitool' to update your system.
