[Morten Linderud]

Arch Linux Security Advisory ASA-202102-39
==========================================

Severity: High
Date    : 2021-02-27
CVE-ID  : CVE-2020-5208
Package : ipmitool
Type    : arbitrary code execution
Remote  : Yes
Link    : https://security.archlinux.org/AVG-1596

Summary
=======

The package ipmitool before version 1.8.18-7 is vulnerable to arbitrary
code execution.

Resolution
==========

Upgrade to 1.8.18-7.

# pacman -Syu "ipmitool>=1.8.18-7"

The problem has been fixed upstream but no release is available yet.

Workaround
==========

None.

Description
===========

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.

Impact
======

A remote server could execute arbitrary code on the client.
