How to fix?

Upgrade SLES:16.0.0 openssl-3-livepatches to version 0.6-160000.1.1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream openssl-3-livepatches package and not the openssl-3-livepatches package as distributed by SLES. See How to fix? for SLES:16.0.0 relevant fixed versions and status.

Issue summary: In a server or client configuration with RFC7250 Raw Public Keys (RPKs) enabled, and only the private key (with no associated certificate) configured locally, a NULL pointer dereference may occur when the remote peer solicits raw public keys and also sends the typically omitted "signature_algorithms_cert" TLS extension.

Impact summary: The impact is limited to a possible Denial of Service as a result of an application abort, no data disclosure or remote command execution are possible.

CWE: CWE-476: NULL Pointer Dereference

Description: While a passing comment in sample code in the documentation suggests that key-only RPK configurations are supported, the best-practice RPK configuration is to always configure a corresponding certificate (possibly self-signed or signed by any convenient CA).

When the private key is configured along with a matching certificate, the "signature_algorithms_cert" extension is handled reliably even without the fix, and peer clients or servers that don't support raw public keys may be able to complete a TLS connection by pinning or verifying the corresponding certificate or its public key.

Deployments that prefer to configure just a private key with no certificate need to upgrade to an updated release as noted below.

FIPS impact: no

No FIPS modules are affected by this issue, as the SSL protocol implementation is outside the OpenSSL FIPS module boundary.
