A vulnerability has been found in Libtirpc and RPCBind which may allow a remote attacker to cause a Denial of Service condition.
| Package | Arch | Vulnerable | Unaffected |
|---|---|---|---|
| net-libs/libtirpc | * | < 1.0.1-r1 | >= 1.0.1-r1 |
| net-nds/rpcbind | * | < 0.2.4-r1 | >= 0.2.4-r1 |
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"
A buffer overflow in RPCBind might allow remote attackers to cause a Denial of Service.

The RPCBind utility is a server that converts RPC program numbers into universal addresses.
A use-after-free vulnerability was discovered in RPCBind’s svc_dodestroy function when trying to free a corrupted xprt->xp_netid pointer.
A remote attacker could possibly cause a Denial of Service condition.
There is no known workaround at this time.
All RPCBind users should upgrade to the latest version:
