What is CVE-2018-10907?

The GlusterFS server is susceptible to multiple stack-based buffer overflow vulnerabilities attributed to its use of fixed-size buffers allocated via 'alloca(3)' in the server-rpc-fopc.c file. An authenticated attacker could potentially exploit this vulnerability by mounting a Gluster volume and sending a string that exceeds the predetermined buffer size, leading to application crashes or risking arbitrary code execution.
