"The version of krita installed on the remote host is prior to 5.0.2. It is, therefore, affected by a vulnerability as
referenced in the SSA:2026-093-02 advisory.

    New krita packages are available for Slackware 15.0 to fix a security issue.

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

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