Nfs Utils
Monthly
Local denial of service in the nfs-utils fsidd daemon affects Red Hat Enterprise Linux 6, 7, 8, 9, and 10 as well as Red Hat OpenShift Container Platform 4; an authenticated local user with access to the fsidd Unix domain socket can send a malformed request that omits required arguments, triggering a CWE-617 assertion failure and crashing the daemon. The service remains unavailable for filesystem identifier lookups until restarted, giving this a CVSS 3.1 score of 5.5 (AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H). No public exploit code has been identified at time of analysis.
A vulnerability was recently discovered in the rpc.mountd daemon in the nfs-utils package for Linux, that allows a NFSv3 client to escalate the privileges assigned to it in the /etc/exports file at mount time. [CVSS 6.5 MEDIUM]
The nfs-utils package in SUSE Linux Enterprise Server 12 before and including version 1.3.0-34.18.1 and in SUSE Linux Enterprise Server 15 before and including version 2.1.1-6.10.2 the directory. Rated critical severity (CVSS 9.8), this vulnerability is remotely exploitable, no authentication required, low attack complexity. This Incorrect Default Permissions vulnerability could allow attackers to access resources due to overly permissive default settings.
rpc-gssd in nfs-utils before 1.2.8 performs reverse DNS resolution for server names during GSSAPI authentication, which might allow remote attackers to read otherwise-restricted files via DNS. Rated low severity (CVSS 3.2). No vendor patch available.
