Upgrade RHEL:8
libcurl-devel
to version 0:7.61.1-18.el8_4.2 or higher.

.
NVD Description
Note: Versions mentioned in the description apply only to the upstream libcurl-devel
package and not the libcurl-devel
package as distributed by RHEL
.
See How to fix?
for RHEL:8
relevant fixed versions and status.
A user can tell curl >= 7.20.0 and <= 7.78.0 to require a successful upgrade to TLS when speaking to an IMAP, POP3 or FTP server (--ssl-reqd
on the command line orCURLOPT_USE_SSL
set to CURLUSESSL_CONTROL
or CURLUSESSL_ALL
withlibcurl). This requirement could be bypassed if the server would return a properly crafted but perfectly legitimate response.This flaw would then make curl silently continue its operations withoutTLS contrary to the instructions and expectations, exposing possibly sensitive data in clear text over the network.
