OpenSSL: Denial of service

Background

OpenSSL is an Open Source toolkit implementing the Secure Sockets Layer (SSL v2/v3) and Transport Layer Security (TLS v1/v1.1/v1.2/v1.3) as well as a general purpose cryptography library.

Description

A null pointer dereference flaw was found in OpenSSL.

Impact

A remote attacker, able to control the arguments of the GENERAL_NAME_cmp function in an application linked against OpenSSL, could possibly cause a Denial of Service condition.

Workaround

There is no known workaround at this time.

Resolution

All OpenSSL users should upgrade to the latest version:

 # emerge --sync
 # emerge --ask --oneshot --verbose ">=dev-libs/openssl-1.1.1i"
