The remote Ubuntu 16.04 ESM / 18.04 ESM host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-4770-1 advisory.

  - The __socket_proto_state_machine function in GlusterFS 3.5 allows remote attackers to cause a denial of     service (infinite loop) via a 00000000 fragment header. (CVE-2014-3619)

  - glusterfs is vulnerable to privilege escalation on gluster server nodes. An authenticated gluster client     via TLS could use gluster cli with --remote-host command to add it self to trusted storage pool and     perform privileged gluster operations like adding other machines to trusted storage pool, start, stop, and     delete volumes. (CVE-2018-10841)

  - A privilege escalation flaw was found in gluster 3.x snapshot scheduler. Any gluster client allowed to     mount gluster volumes could also mount shared gluster storage volume and escalate privileges by scheduling     malicious cronjob via symlink. (CVE-2018-1088)

  - 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. (CVE-2018-10904)

  - 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. (CVE-2018-10907)

  - A flaw was found in the way dic_unserialize function of glusterfs does not handle negative key length     values. An attacker could use this flaw to read memory from other locations into the stored dict value.
    (CVE-2018-10911)

  - An information disclosure vulnerability was discovered in glusterfs server. An attacker could issue a     xattr request via glusterfs FUSE to determine the existence of any file. (CVE-2018-10913)

  - 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. (CVE-2018-10914)

  - 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. (CVE-2018-10923)

  - It was discovered that fsync(2) system call in glusterfs client code leaks memory. An authenticated     attacker could use this flaw to launch a denial of service attack by making gluster clients consume memory     of the host machine. (CVE-2018-10924)

  - A flaw was found in RPC request using gfs3_mknod_req supported by glusterfs server. An authenticated     attacker could use this flaw to write files to an arbitrary location via path traversal and execute     arbitrary code on a glusterfs server node. (CVE-2018-10926)

  - A flaw was found in RPC request using gfs3_lookup_req in glusterfs server. An authenticated attacker could     use this flaw to leak information and execute remote denial of service by crashing gluster brick process.
    (CVE-2018-10927)

  - 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. (CVE-2018-10928)

  - A flaw was found in RPC request using gfs2_create_req in glusterfs server. An authenticated attacker could     use this flaw to create arbitrary files and execute arbitrary code on glusterfs server nodes.
    (CVE-2018-10929)

  - A flaw was found in RPC request using gfs3_rename_req in glusterfs server. An authenticated attacker could     use this flaw to write to a destination outside the gluster volume. (CVE-2018-10930)

  - 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-2018-14651)

  - 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-2018-14652)

  - 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-2018-14653)

  - 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-2018-14654)

  - The Gluster file system through versions 4.1.4 and 3.1.2 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-2018-14659)

  - A flaw was found in glusterfs server through versions 4.1.4 and 3.1.2 which allowed repeated usage of     GF_META_LOCK_KEY xattr. A remote, authenticated attacker could use this flaw to create multiple locks for     single inode by using setxattr repetitively resulting in memory exhaustion of glusterfs server node.
    (CVE-2018-14660)

  - It was found that usage of snprintf function in feature/locks translator of glusterfs server 3.8.4, as     shipped with Red Hat Gluster Storage, was vulnerable to a format string attack. A remote, authenticated     attacker could use this flaw to cause remote denial of service. (CVE-2018-14661)
