CVE-2018-14651

It was found that the fix for CVE-2018-10927, CVE-2018-10928, CVE-2018-10929, CVE-2018-10930, and CVE-2018-10926 was incomplete. A remote, authenticated attacker could use one of these flaws to execute arbitrary code, create arbitrary files, or cause denial of service on glusterfs server nodes via symlinks to relative paths.

CVE-2018-14652

The Gluster file system 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-2018-14653

The Gluster file system 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-2018-14659

The Gluster file system is vulnerable to a denial of service attack via use of the GF_XATTR_IOSTATS_DUMP_KEY xattr. A remote, authenticated attacker could exploit this by mounting a Gluster volume and repeatedly calling 'setxattr(2)' to trigger a state dump and create an arbitrary number of files in the server's runtime directory.

CVE-2018-14661

It was found that usage of snprintf function in feature/locks translator of glusterfs server was vulnerable to a format string attack. A remote, authenticated attacker could use this flaw to cause remote denial of service.

For Debian 8 Jessie, these problems have been fixed in version 3.5.2-2+deb8u5.

We recommend that you upgrade your glusterfs packages.
