CVE-2018-14653 [HIGH] CWE-122 CVE-2018-14653: The Gluster file system through versions 4.1.4 and 3.12 is vulnerable to a heap-based buffer overflo The Gluster file system through versions 4.1.4 and 3.12 is vulnerable to a heap-based buffer overflow in the '__server_getspec' function via the 'gf_getspec_req' RPC message. A remote authenticated attacker could exploit this to cause a denial of service or other potential unspecified impact.

CVE-2018-14652 [MEDIUM] CWE-120 CVE-2018-14652: The Gluster file system through versions 3.12 and 4.1.4 is vulnerable to a buffer overflow in the 'f The Gluster file system through versions 3.12 and 4.1.4 is vulnerable to a buffer overflow in the 'features/index' translator via the code handling the 'GF_XATTR_CLRLK_CMD' xattr in the 'pl_getxattr' function. A remote authenticated attacker could exploit this on a mounted volume to cause a denial of service.

CVE-2018-14654 [MEDIUM] CWE-22 CVE-2018-14654: The Gluster file system through version 4.1.4 is vulnerable to abuse of the 'features/index' transla The Gluster file system through version 4.1.4 is vulnerable to abuse of the 'features/index' translator. A remote attacker with access to mount volumes could exploit this via the 'GF_XATTROP_ENTRY_IN_KEY' xattrop to create arbitrary, empty files on the target server.

CVE-2018-1087 [HIGH] CWE-250 CVE-2018-1087: kernel KVM before versions kernel 4.16, kernel 4.16-rc7, kernel 4.17-rc1, kernel 4.17-rc2 and kernel kernel KVM before versions kernel 4.16, kernel 4.16-rc7, kernel 4.17-rc1, kernel 4.17-rc2 and kernel 4.17-rc3 is vulnerable to a flaw in the way the Linux kernel's KVM hypervisor handled exceptions delivered after a stack switch operation via Mov SS or Pop SS instructions. During the stack switch operation, the processor did not deliver interrupts and e
