SUSE SLES12 Security Update : curl (SUSE-SU-2021:1763-1)

low Nessus Plugin ID 150019

Language:

Synopsis

The remote SUSE host is missing one or more security updates.

Description

This update for curl fixes the following issues :

CVE-2021-22898: Fixed curl TELNET stack contents disclosure (bsc#1186114).

Allow partial chain verification [jsc#SLE-17956]

- Have intermediate certificates in the trust store be treated as trust-anchors, in the same way as self-signed root CA certificates are. This allows users to verify servers using the intermediate cert only, instead of needing the whole chain.

- Set FLAG_TRUSTED_FIRST unconditionally.

- Do not check partial chains with CRL check.

Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

To install this SUSE Security Update use the SUSE recommended installation methods like YaST online_update or 'zypper patch'.
