ArchLinux: 202102-39: ipmitool: arbitrary code execution
Summary
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.
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.
