UBUNTU-CVE-2020-11934

It was discovered that snapctl user-open allowed altering the $XDGDATADIRS environment variable when calling the system xdg-open. OpenURL in usersession/userd/launcher.go would alter $XDGDATADIRS to append a path to a directory controlled by the calling snap. A malicious snap could exploit this t...

DEBIAN-CVE-2019-7304

Canonical snapd before version 2.37.1 incorrectly performed socket owner validation, allowing an attacker to run arbitrary commands as root. This issue affects: Canonical snapd versions prior to 2.37.1...

DEBIAN-CVE-2019-7303

A vulnerability in the seccomp filters of Canonical snapd before version 2.37.4 allows a strict mode snap to insert characters into a terminal on a 64-bit host. The seccomp rules were generated to match 64-bit ioctl2 commands on a 64-bit platform; however, the Linux kernel only uses the lower 32...

USN-3917-1 snapd vulnerability

The snapd default seccomp filter for strict mode snaps blocks the use of the ioctl system call when used with TIOCSTI as the second argument to the system call. Jann Horn discovered that this restriction could be circumvented on 64 bit architectures. A malicious snap could exploit this to bypass...

USN-3887-1 snapd vulnerability

Chris Moberly discovered that snapd versions 2.28 through 2.37 incorrectly validated and parsed the remote socket address when performing access controls on its UNIX socket. A local attacker could use this to access privileged socket APIs and obtain administrator privileges. On Ubuntu systems wit...

snapd security bypass vulnerability

snapd is a tool used in Linux to create application snapshots. A security vulnerability exists in snapd versions 2.27 through 2.29.2, which stems from a program that creates the snap logs command to invoke journalctl without matching the parameters.An attacker could use this vulnerability to bypa...

UBUNTU-CVE-2017-14178

In snapd 2.27 through 2.29.2 the 'snap logs' command could be made to call journalctl without match arguments and therefore allow unprivileged, unauthenticated users to bypass systemd-journald's access restrictions...
