UBUNTU-CVE-2018-18955

In the Linux kernel 4.15.x through 4.19.x before 4.19.2, mapwrite in kernel/usernamespace.c allows privilege escalation because it mishandles nested user namespaces with more than 5 UID or GID ranges. A user who has CAPSYSADMIN in an affected user namespace can bypass access controls on resources...

CVE-2018-6552 Apport treats the container PID as the global PID when /proc/<global_pid>/ is missing

Apport does not properly handle crashes originating from a PID namespace allowing local users to create certain files as root which an attacker could leverage to perform a denial of service via resource exhaustion, possibly gain root privileges, or escape from containers. The issamens function...

glibc 'realpath()' Privilege Escalation

This module attempts to gain root privileges on Linux systems by abusing a vulnerability in GNU C Library glibc version 2.26 and prior. This module uses halfdog's RationalLove exploit to exploit a buffer underflow in glibc realpath and create a SUID root shell. The exploit has offsets for glibc...

Linux 4.4.0 < 4.4.0-53 - AF_PACKET chocobo_root Privilege Escalation Exploit

kernel: net: double-free and memory corruption in get_net_ns_by_id()

A use-after-free vulnerability was found in a network namespaces code affecting the Linux kernel since v4.0-rc1 through v4.15-rc5. The function getnetnsbyid does not check for the net::count value after it has found a peer network in netnsids idr which could lead to double free and memory...

kernel: Missing capabilities check in net/netfilter/nfnetlink_cthelper.c allows for unprivileged access to systemwide nfnl_cthelper_list structure

The net/netfilter/nfnetlinkcthelper.c function in the Linux kernel through 4.14.4 does not require the CAPNETADMIN capability for new, get, and del operations. This allows local users to bypass intended access restrictions because the nfnlcthelperlist data structure is shared across all net...
