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:
- CVE-2021-33910: Fixed a denial of service (stack exhaustion) in systemd (PID 1) (bsc#1188063)
Other fixes:
- mount-util: shorten the loop a bit (#7545) - mount-util: do not use the official MAX_HANDLE_SZ (#7523) - mount-util: tape over name_to_handle_at() flakiness (#7517) (bsc#1184761) - mount-util: fix bad indenting - mount-util: EOVERFLOW might have other causes than buffer size issues - mount-util: fix error propagation in fd_fdinfo_mnt_id() - mount-util: drop exponential buffer growing in name_to_handle_at_loop() - udev: port udev_has_devtmpfs() to use path_get_mnt_id() - mount-util: add new path_get_mnt_id() call that queries the mnt ID of a path - mount-util: add name_to_handle_at_loop() wrapper around name_to_handle_at() - mount-util: accept that name_to_handle_at() might fail with EPERM (#5499) - basic: fallback to the fstat if we don't have access to the /proc/self/fdinfo - sysusers: use the usual comment style - test/TEST-21-SYSUSERS: add tests for new functionality - sysusers: allow admin/runtime overrides to command-line config - basic/strv: add function to insert items at position - sysusers: allow the shell to be specified - sysusers: move various user credential validity checks to src/basic/ - man: reformat table in sysusers.d(5) - sysusers: take configuration as positional arguments - sysusers: emit a bit more info at debug level when locking fails - sysusers: allow force reusing existing user/group IDs (#8037) - sysusers: ensure GID in uid:gid syntax exists - sysusers: make ADD_GROUP always create a group - test: add TEST-21-SYSUSERS test - sysuser: use OrderedHashmap - sysusers: allow uid:gid in sysusers.conf files - sysusers: fix memleak (#4430) - 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. - Expect 644 permissions for /usr/lib/udev/compat-symlink-generation (bsc#1185807) - systemctl: add --value option - execute: make sure to call into PAM after initializing resource limits (bsc#1184967) - rlimit-util: introduce setrlimit_closest_all() - system-conf: drop reference to ShutdownWatchdogUsec= - core: rename ShutdownWatchdogSec to RebootWatchdogSec (bsc#1185331) - Return -EAGAIN instead of -EALREADY from unit_reload (bsc#1185046) - rules: don't ignore Xen virtual interfaces anymore (bsc#1178561) - write_net_rules: set execute bits (bsc#1178561) - udev: rework network device renaming - Revert "Revert "udev: network device renaming - immediately give up if the target name isn't available""
