  script_tag(name:"insight", value:"This update is based on the upstream 5.7.19 kernel and fixes at least the
following security issue:

In the Linux kernel 5.0.21 and 5.3.11, mounting a crafted btrfs filesystem
image, performing some operations, and then making a syncfs system call can
lead to a use-after-free in try_merge_free_space in
fs/btrfs/free-space-cache.c because the pointer to a left data structure can
be the same as the pointer to a right data structure (CVE-2019-19448).

A memory out-of-bounds read flaw was found in the Linux kernel's ext3/ext4
filesystem, in the way it accesses a directory with broken indexing. This flaw
allows a local user to crash the system if the directory exists. The highest
threat from this vulnerability is to system availability (CVE-2020-14314).

For other upstream fixes and changes in this update, see the referenced
changelogs.

Also, the wireguard-tools package has been updated to version 1.0.20200827.");
