An update that solves one vulnerability and has 6 fixes is now available.
Description:
This update for systemd fixes the following issues:
Security issues fixed:
o CVE-2021-33910: Fixed a denial of service (stack exhaustion) in systemd
(PID 1) (bsc#1188063)
Other fixes:
o mount-util: shorten the loop a bit (#7545)
o mount-util: do not use the official MAX_HANDLE_SZ (#7523)
o mount-util: tape over name_to_handle_at() flakiness (#7517) (bsc#1184761)
o mount-util: fix bad indenting
o mount-util: EOVERFLOW might have other causes than buffer size issues
o mount-util: fix error propagation in fd_fdinfo_mnt_id()
o mount-util: drop exponential buffer growing in name_to_handle_at_loop()
o udev: port udev_has_devtmpfs() to use path_get_mnt_id()
o mount-util: add new path_get_mnt_id() call that queries the mnt ID of a
path
o mount-util: add name_to_handle_at_loop() wrapper around name_to_handle_at()
o mount-util: accept that name_to_handle_at() might fail with EPERM (#5499)
o basic: fallback to the fstat if we don't have access to the /proc/self/
fdinfo
o sysusers: use the usual comment style
o test/TEST-21-SYSUSERS: add tests for new functionality
o sysusers: allow admin/runtime overrides to command-line config
o basic/strv: add function to insert items at position
o sysusers: allow the shell to be specified
o sysusers: move various user credential validity checks to src/basic/
o man: reformat table in sysusers.d(5)
o sysusers: take configuration as positional arguments
o sysusers: emit a bit more info at debug level when locking fails
o sysusers: allow force reusing existing user/group IDs (#8037)
o sysusers: ensure GID in uid:gid syntax exists
o sysusers: make ADD_GROUP always create a group
o test: add TEST-21-SYSUSERS test
o sysuser: use OrderedHashmap
o sysusers: allow uid:gid in sysusers.conf files
o sysusers: fix memleak (#4430)
o These commits implement the option '--replace' for systemd-sysusers so
%sysusers_create_package can be introduced in SLE and packages can rely on
this rpm macro without wondering whether the macro is available on the
different target the package is submitted to.
o Expect 644 permissions for /usr/lib/udev/compat-symlink-generation (bsc#
1185807)
o systemctl: add --value option
o execute: make sure to call into PAM after initializing resource limits (bsc
#1184967)
o rlimit-util: introduce setrlimit_closest_all()
o system-conf: drop reference to ShutdownWatchdogUsec=
o core: rename ShutdownWatchdogSec to RebootWatchdogSec (bsc#1185331)
o Return -EAGAIN instead of -EALREADY from unit_reload (bsc#1185046)
o rules: don't ignore Xen virtual interfaces anymore (bsc#1178561)
o write_net_rules: set execute bits (bsc#1178561)
o udev: rework network device renaming
o Revert "Revert "udev: network device renaming - immediately give up if the
target name isn't available""
