Summary
CVE-2023-27536 affecting package curl for versions less than 8.0.1-1
Details

An authentication bypass vulnerability exists libcurl <8.0.0 in the connection reuse feature which can reuse previously established connections with incorrect user permissions due to a failure to check for changes in the CURLOPTGSSAPIDELEGATION option.
