Arch Linux Security Advisory ASA-201705-5
Date : 2017-05-07
CVE-ID : CVE-2017-8779
Package : libtirpc
Type : denial of service
Remote : Yes
Link : https://security.archlinux.org/AVG-262
The package libtirpc before version 1.0.1-3 is vulnerable to denial of
Upgrade to 1.0.1-3.
# pacman -Syu "libtirpc>=1.0.1-3"
The problem has been fixed upstream but no release is available yet.
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
A remote attacker is able to send specially crafted input to leak
memory, possibly leading to denial of service.
