Upgrade SLES:15.0 libcurl4-32bit to version 7.60.0-3.42.1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream libcurl4-32bit package and not the libcurl4-32bit package as distributed by SLES. See How to fix? for SLES:15.0 relevant fixed versions and status.

curl 7.1.1 to and including 7.75.0 is vulnerable to an "Exposure of Private Personal Information to an Unauthorized Actor" by leaking credentials in the HTTP Referer: header. libcurl does not strip off user credentials from the URL when automatically populating the Referer: HTTP request header field in outgoing HTTP requests, and therefore risks leaking sensitive data to the server that is the target of the second HTTP request.
