CVE-2018-1068

kernel: Out-of-bounds write via userland offsets in ebt_entry struct in netfilter/ebtables.c

A flaw was found in the Linux 4.x kernel's implementation of 32-bit syscall interface for bridging. This allowed a privileged user to arbitrarily write to a limited range of kernel memory.

undertow: HTTP header injection using CRLF with UTF-8 Encoding (incomplete fix of CVE-2016-4993)

In Undertow before versions 7.1.2.CR1, 7.1.2.GA it was found that the fix for CVE-2016-4993 was incomplete and Undertow web server is vulnerable to the injection of arbitrary HTTP headers, and also response splitting, due to insufficient sanitization and validation of user input before the input is used as part of an HTTP header value.

dpdk: Information exposure in unchecked guest physical to host virtual address translations

The DPDK vhost-user interface does not check to verify that all the requested guest physical range is mapped and contiguous when performing Guest Physical Addresses to Host Virtual Addresses translations. This may lead to a malicious guest exposing vhost-user backend process memory. All versions before 18.02.1 are vulnerable.

CVE-2018-18559

kernel: Use-after-free due to race condition in AF_PACKET implementation

In the Linux kernel through 4.19, a use-after-free can occur due to a race condition between fanout_add from setsockopt and bind on an AF_PACKET socket. This issue exists because of the 15fe076edea787807a7cdc168df832544b58eba6 incomplete fix for a race condition. The code mishandles a certain multithreaded case involving a packet_do_bind unregister action followed by a packet_notifier register action. Later, packet_release operates on only one of the two applicable linked lists. The attacker can achieve Program Counter control.

kernel: userfaultfd bypasses tmpfs file permissions

The userfaultfd implementation in the Linux kernel before 4.19.7 mishandles access control for certain UFFDIO_ ioctl calls, as demonstrated by allowing local users to write data into holes in a tmpfs file (if the user has read-only access to that file, and that file contains holes), related to fs/userfaultfd.c and mm/userfaultfd.c.

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.

glusterfs: Unlimited file creation via "GF_XATTR_IOSTATS_DUMP_KEY" xattr allows for denial of service

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-2018-13405

kernel: Missing check in fs/inode.c:inode_init_owner() does not clear SGID bit on non-directories for non-members

The inode_init_owner function in fs/inode.c in the Linux kernel through 3.16 allows local users to create files with an unintended group ownership, in a scenario where a directory is SGID to a certain group and is writable by a user who is not a member of that group. Here, the non-member can trigger creation of a plain file whose group ownership is that group. The intended behavior was that the non-member can trigger creation of a directory (but not a plain file) whose group ownership is that group. The non-member can escalate privileges by making the plain file executable and SGID.
