Description
slpd-lite is a unicast SLP UDP server. Any OpenBMC system that includes the slpd-lite package is impacted. Installing this package is the default when building OpenBMC. Nefarious users can send slp packets to the BMC using UDP port 427 to cause memory overflow issues within the slpd-lite daemon on the BMC. Patches will be available in the latest openbmc/slpd-lite repository.
