CVE-ID : CVE-2017-8779
Package : rpcbind
Type : denial of service
Remote : Yes
Link : https://security.archlinux.org/AVG-261
The package rpcbind before version 0.2.4-3 is vulnerable to denial of
service.
Upgrade to 0.2.4-3.
The problem has been fixed upstream but no release is available yet.
None.
It was found that libtirpc and libntirpc fails to free a buffer
allocated for parsing XDR blocks when parsing fails due to insufficient
input data being available. A specially crafted message sent to a
service such as rpcbind results in a memory leak, causing the
application to crash or other processes to be impacted via the OOM
killer.
A remote attacker is able to send specially crafted input to leak
memory, possibly leading to denial of service.
