    Changes in htop:

    - Update to version 3.5.3:
      * Improve the htoprc settings parser to avoid segfaults on
        tampered configuration files (sanitised sort keys, validated
        configuration invariants, NULL safety for header columns and
        screens)
      * Add zswap pool usage meters
      * Fix out-of-bounds access when parsing the power supply type
        (Linux)
      * Mark a CPU offline when it is unplugged from the middle and
        release its data on hot-unplug (Linux)
      * Fix a Clang MemorySanitizer-reported issue
      * Exit follow mode when a search or filter is cancelled
      * Fix blank STARTTIME and wrong ELAPSED for threads (Darwin)
      * Use strchr instead of strstr in XUtils
      * Document the CPU meter segments in the man page and add an
        External Libraries section covering libnl-3/libnl-genl-3
    - CVE-2024-37676: out-of-bounds access in
      Header_populateFromSettings reachable from a tampered htoprc;
      the settings parser hardening above is what upstream lists as
      covering it. openSUSE is assessed not affected (boo#1226729)

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
