glusterfs: Stack-based buffer overflow in server-rpc-fops.c allows remote attackers to execute arbitrary code

Published Sep 4, 2018

Description

It was found that glusterfs server is vulnerable to multiple stack based buffer overflows due to functions in server-rpc-fopc.c allocating fixed size buffers using 'alloca(3)'. An authenticated attacker could exploit this by mounting a gluster volume and sending a string longer that the fixed buffer size to cause crash or potential code execution.

Remediation

Red Hat statement

This issue did not affect Red Hat Enterprise Linux 6 and 7 as the flaw is present in glusterfs-server, which is not shipped there. This flaw affects glusterfs versions included in Red Hat Virtualization 4 Hypervisor. However, in recommended configurations, the vulnerability is only exposed to hypervisor administrators and can not be exploited from virtual machines or other hosts on the network. For Red Hat Virtualization, Product Security has rated this flaw as Moderate. For additional information, refer to the Issue Severity Classification: https://access.redhat.com/security/updates/classification/.

Red Hat mitigation

To limit exposure of gluster server nodes : 1. gluster server should be on LAN and not reachable from public networks. 2. Use gluster auth.allow and auth.reject. 3. Use TLS certificates to authenticate gluster clients. caveat: This does not protect from attacks by authenticated gluster clients.
