CVE-2018-18710 3 Canonical, Debian, Linux 3 Ubuntu Linux, Debian Linux, Linux Kernel 2019-04-03 2.1 LOW 5.5 MEDIUM
An issue was discovered in the Linux kernel through 4.19. An information leak in cdrom_ioctl_select_disc in drivers/cdrom/cdrom.c could be used by local attackers to read kernel memory because a cast from unsigned long to int interferes with bounds checking. This is similar to CVE-2018-10940 and CVE-2018-16658.
CVE-2018-12896 3 Canonical, Debian, Linux 3 Ubuntu Linux, Debian Linux, Linux Kernel 2019-04-03 2.1 LOW 5.5 MEDIUM
An issue was discovered in the Linux kernel through 4.17.3. An Integer Overflow in kernel/time/posix-timers.c in the POSIX timer code is caused by the way the overrun accounting works. Depending on interval and expiry time values, the overrun can be larger than INT_MAX, but the accounting is int based. This basically makes the accounting values, which are visible to user space via timer_getoverrun(2) and siginfo::si_overrun, random. For example, a local user can cause a denial of service (signed integer overflow) via crafted mmap, futex, timer_create, and timer_settime system calls.
CVE-2018-1000100 2 Canonical, Gpac Project 2 Ubuntu Linux, Gpac 2019-04-03 6.8 MEDIUM 7.8 HIGH
GPAC MP4Box version 0.7.1 and earlier contains a Buffer Overflow vulnerability in src/isomedia/avc_ext.c lines 2417 to 2420 that can result in Heap chunks being modified, this could lead to RCE. This attack appear to be exploitable via an attacker supplied MP4 file that when run by the victim may result in RCE.
CVE-2018-18021 3 Canonical, Debian, Linux 3 Ubuntu Linux, Debian Linux, Linux Kernel 2019-04-03 3.6 LOW 7.1 HIGH
arch/arm64/kvm/guest.c in KVM in the Linux kernel before 4.18.12 on the arm64 platform mishandles the KVM_SET_ON_REG ioctl. This is exploitable by attackers who can create virtual machines. An attacker can arbitrarily redirect the hypervisor flow of control (with full register control). An attacker can also cause a denial of service (hypervisor panic) via an illegal exception return. This occurs because of insufficient restrictions on userspace access to the core register file, and because PSTATE.M validation does not prevent unintended execution modes.
CVE-2018-10916 3 Canonical, Lftp Project, Opensuse 3 Ubuntu Linux, Lftp, Leap 2019-04-02 7.8 HIGH 6.5 MEDIUM
It has been discovered that lftp up to and including version 4.8.3 does not properly sanitize remote file names, leading to a loss of integrity on the local system when reverse mirroring is used. A remote attacker may trick a user to use reverse mirroring on an attacker controlled FTP server, resulting in the removal of all files in the current working directory of the victim's system.
CVE-2016-5824 3 Canonical, Libical Project, Redhat 8 Ubuntu Linux, Libical, Enterprise Linux Desktop and 5 more 2019-04-02 4.3 MEDIUM 5.5 MEDIUM
