EulerOS 2.0 SP5 : openssl111d (EulerOS-SA-2020-1613)

high Nessus Plugin ID 137031

Synopsis

The remote EulerOS host is missing a security update.

Description

According to the version of the openssl111d packages installed, the EulerOS installation on the remote host is affected by the following vulnerability :

- Server or client applications that call the SSL_check_chain() function during or after a TLS 1.3 handshake may crash due to a NULL pointer dereference as a result of incorrect handling of the 'signature_algorithms_cert' TLS extension. The crash occurs if an invalid or unrecognised signature algorithm is received from the peer. This could be exploited by a malicious peer in a Denial of Service attack. OpenSSL version 1.1.1d, 1.1.1e, and 1.1.1f are affected by this issue. This issue did not affect OpenSSL versions prior to 1.1.1d. Fixed in OpenSSL 1.1.1g (Affected 1.1.1d-1.1.1f).(CVE-2020-1967)

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

Solution

Update the affected openssl111d package.
