Synopsis

The remote EulerOS host is missing multiple security updates.

Description

According to the versions of the nss packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

 - A cached side channel attack during handshakes using RSA encryption could allow for the decryption of encrypted content. This is a variant of the Adaptive Chosen Ciphertext attack (AKA Bleichenbacher attack) and affects all NSS versions prior to NSS 3.41.(CVE-2018-12404)

 - Empty or malformed p256-ECDH public keys may trigger a segmentation fault due values being improperly sanitized before being copied into memory and used.
 This vulnerability affects Firefox ESR < 60.8, Firefox < 68, and Thunderbird < 60.8.(CVE-2019-11729)

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 nss packages.
