The RPCBind utility is a server that converts RPC program numbers into universal addresses.
Libtirpc is a port of Suns Transport-Independent RPC library to Linux.
It was found that due to the way RPCBind uses libtirpc (libntirpc), a memory leak can occur when parsing specially crafted XDR messages.
A remote attacker could send thousands of messages to RPCBind, possibly resulting in a Denial of Service condition.
There is no known workaround at this time.
All RPCBind users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=net-nds/rpcbind-0.2.4-r1"
All Libtirpc users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=net-libs/libtirpc-1.0.1-r1"
