slackware-current/source/n/openssl11/0001-openssl-1.1.1x_CVE-2023-5678_CVE-2024-0727.patch
Patrick J Volkerding 5df6155d42 Wed Jul 17 19:29:24 UTC 2024

  Apply patches to fix CVEs that were fixed by the 1.1.1{x,y,za} releases that
  were only available to subscribers to OpenSSL's premium extended support.
  These patches were prepared by backporting commits from the OpenSSL-3.0 repo.
  The reported version number has been updated so that vulnerability scanners
  calm down. All of these issues were considered to be of low severity.
  We probably won't keep 1.1.1 in -current for long anyway, but might as well
  patch it first. :-)
  Thanks to Ken Zalewski for the patches!
