patches/packages/libcaca-0.99.beta20-x86_64-1_slack15.0.txz:  Upgraded.
  Fixed a crash bug (a crafted file defining width of zero leads to divide by
  zero and a crash). Seems to be merely a bug rather than a security issue, but
  I'd been meaning to get beta20 building so this was a good excuse.
  Thanks to marav.
  For more information, see:
    https://www.cve.org/CVERecord?id=CVE-2022-0856
  (* Security fix *)
