CVE-2018-10907

Published: 4 September 2018

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.

From the Ubuntu Security Team

It was discovered that GlusterFS incorrectly handled mounting volumes. An attacker could possibly use this issue to cause a denial of service or run arbitrary code.
