## Description:

This update for wicked fixes the following issues:

Update to version 0.6.79.

  * CVE-2026-44932: indirect remote shell command injection due to insufficient
    sanitization of DHCP options written to `/run/wicked/leaseinfo.*` files
    (bsc#1265221).
  * CVE-2026-71401: out-of-bounds read due to IP length underflow in checksum
    handling of DHCPv4 capture parsing (bsc#1274627).
  * CVE-2026-71402: out-of-bounds read due to DHCP option reader being extended
    beyond provided allocation in DHCPv4 capture parsing (bsc#1274627).

Changes for wicked:

  * Version 0.6.79:
  * Fix to escape single-quotes in leaseinfo dump output used by the `wicked
    test dhcp4` and `wicked test dhcp6` and written to the
    `/run/wicked/leaseinfo.*` files, e.g. to pass them to `netconfig`.
  * Fix `posix-tz-dbname` and `tz-string` option processing checks to permit
    only valid characters according to RFC4833.
  * Discard string values containing single-quotes in other options.
  * Trigger to regenerate `initrd` that may contain wicked binaries on updates
    from wicked versions <= 0.6.78.
  * Version 0.6.78:
  * `man`: small fixes in wireless manpage (gh#opensuse/wicked#1053)
  * `rtnetlink`: fix `RTM_NEWLINK` name resolution in debug
    (gh#opensuse/wicked#1052)
  * Add support for IPVLAN/IPVTAP (jsc#PED-1942, gh#opensuse/wicked#1050,
    gh#opensuse/wicked#1051)
  * `fsm`: remove children reference array from worker (gh#opensuse/wicked#1049)
  * `ifxml`: migrate and generate lower configs/policies
    (gh#opensuse/wicked#1048)
  * `fsm`: use refcount and array macros in worker and policy
    (gh#opensuse/wicked#1047)
  * `route`: use refcounted array and fix error leaks (gh#opensuse/wicked#1046)
  * `utils`: add support for refcounted objects in generic array
    (gh#openSUSE/wicked#1045)
