Synopsis

The remote SUSE host is missing a security update.

Description

The remote SUSE Linux SLES15 / SLES_SAP15 host has a package installed that is affected by a vulnerability as referenced in the SUSE-SU-2022:0872-1 advisory.

Update to 5.62 including new features and bugfixes:

* Security bugfixes
- The 'redirect' option was fixed to properly handle unauthenticated requests (bsc#1182529).
- Fixed a double free with OpenSSL older than 1.1.0.
- Added hardening to systemd service (bsc#1181400).
* New features
- Added new 'protocol = capwin' and 'protocol = capwinctrl' configuration file options.
- Added support for the new SSL_set_options() values.
- Added a bash completion script.
- New 'sessionResume' service-level option to allow or disallow session resumption
- Download fresh ca-certs.pem for each new release.
- New 'protocolHeader' service-level option to insert custom 'connect' protocol negotiation headers.
This feature can be used to impersonate other software (e.g. web browsers).
- 'protocolHost' can also be used to control the client SMTP protocol negotiation HELO/EHLO value.
- Initial FIPS 3.0 support.
- Client-side 'protocol = ldap' support
* Bugfixes
- Fixed a transfer() loop bug.
- Fixed reloading configuration with 'systemctl reload stunnel.service'.
- Fixed incorrect messages logged for OpenSSL errors.
- Fixed 'redirect' with 'protocol'. This combination is not supported by 'smtp', 'pop3' and 'imap' protocols.
- X.509v3 extensions required by modern versions of OpenSSL are added to generated self-signed test certificates.
- Fixed a tiny memory leak in configuration file reload error handling.
- Fixed engine initialization.
- FIPS TLS feature is reported when a provider or container is available, and not when FIPS control API is available.
- Fix configuration reload when compression is used
- Fix test suite fixed not to require external connectivity
