A flaw was found in RPC request using gfs3_symlink_req in glusterfs server which allows symlink destinations to point to file paths outside of the gluster volume. An authenticated attacker could use this flaw to create arbitrary symlinks pointing anywhere on the server and execute arbitrary code on glusterfs server nodes.

It was found that an attacker could issue a xattr request via glusterfs FUSE to cause gluster brick process to crash which will result in a remote denial of service. If gluster multiplexing is enabled this will result in a crash of multiple bricks and gluster volumes.

It was found that the "mknod" call derived from mknod(2) can create files pointing to devices on a glusterfs server node. An authenticated attacker could use this to create an arbitrary device and read data from any device attached to the glusterfs server node.

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.

It was found that glusterfs server does not properly sanitize file paths in the "trusted.io-stats-dump" extended attribute which is used by the "debug/io-stats" translator. Attacker can use this flaw to create files and execute arbitrary code. To exploit this attacker would require sufficient access to modify the extended attributes of files on a gluster volume.
