openSUSE 16 Security Update : wicked (openSUSE-SU-2026:20949-1)

high Nessus Plugin ID 321010

Synopsis

The remote openSUSE host is missing a security update.

Description

The remote openSUSE 16 host has packages installed that are affected by a vulnerability as referenced in the openSUSE- SU-2026:20949-1 advisory.

 Changes in wicked:

 - Update to version 0.6.79
 - Fix an indirect remote shell command injection via unsanitized dhcp strings and leaseinfo dump (bsc#1265221,CVE-2026-44932):
 - 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.
 A netconfig modify filtered for strict key='value' lines without any escaped quotes and discarded these lines already before.
 - 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.

Tenable has extracted the preceding description block directly from the SUSE security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected wicked, wicked-nbft and / or wicked-service packages.
