CVE-2019-7303 is fixed in 9 products on 1 platform, first by golang-github-snapcore-snapd-dev 2.37.4+18.04.1, released March 20, 2019. It is not reported as exploited. Patch Radar priority: Routine.
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 ioctl(2) commands on a 64-bit platform; however, the Linux kernel only uses the lower 32 bits to determine which ioctl(2) commands to run. This issue affects: Canonical snapd versions prior to 2.37.4.
