Does this matter?

High impact if exploited, but EPSS currently rates exploitation as unlikely (3.36%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.

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.
