______________________________________________________________________________
An update that fixes 7 vulnerabilities is now available.
Description:
This update for the Linux Kernel 5.3.18-24_34 fixes several issues.
The following security issues were fixed:
- CVE-2020-29373: Fixed an issue where kernel unsafely handles the root
directory during path lookups, and thus a process inside a mount
namespace can escape to unintended filesystem locations (bsc#1179779).
- CVE-2020-36158: Fixed a potential remote code execution in the Marvell
mwifiex driver (bsc#1180562).
- CVE-2020-0466: Fixed a use-after-free due to a logic error in
do_epoll_ctl and ep_loop_check_proc of eventpoll.c (bnc#1180032.
- CVE-2020-29569: Fixed a use after free due to a logic error
(bsc#1180008).
- CVE-2020-29660: Fixed a locking inconsistency in the tty subsystem that
may have allowed a read-after-free attack against TIOCGSID (bsc#1179877).
- CVE-2020-29661: Fixed a locking issue in the tty subsystem that allowed
a use-after-free attack against TIOCSPGRP (bsc#1179877).
- CVE-2020-29368: Fixed an issue in copy-on-write implementation which
could grant unintended write access because of a race condition in a THP
mapcount check (bsc#1179664).
