EulerOS Virtualization for ARM 64 3.0.6.0 : openssl (EulerOS-SA-2021-2020)
medium Nessus Plugin ID 151159
Synopsis
The remote EulerOS Virtualization for ARM 64 host is missing a security update.Description
According to the version of the openssl packages installed, the EulerOS Virtualization for ARM 64 installation on the remote host is affected by the following vulnerability :- An OpenSSL TLS server may crash if sent a maliciously crafted renegotiation ClientHello message from a client. If a TLSv1.2 renegotiation ClientHello omits the signature_algorithms extension (where it was present in the initial ClientHello), but includes a signature_algorithms_cert extension then a NULL pointer dereference will result, leading to a crash and a denial of service attack. A server is only vulnerable if it has TLSv1.2 and renegotiation enabled (which is the default configuration). OpenSSL TLS clients are not impacted by this issue. All OpenSSL 1.1.1 versions are affected by this issue. Users of these versions should upgrade to OpenSSL 1.1.1k. OpenSSL 1.0.2 is not impacted by this issue. Fixed in OpenSSL 1.1.1k (Affected 1.1.1-1.1.1j).(CVE-2021-3449)
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.
