EulerOS 2.0 SP5 : nginx (EulerOS-SA-2021-2513)

high Nessus Plugin ID 153726

Synopsis

The remote EulerOS host is missing a security update.

Description

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

 - ALPACA is an application layer protocol content confusion attack, exploiting TLS servers implementing different protocols but using compatible certificates, such as multi-domain or wildcard certificates. A MiTM attacker having access to victim's traffic at the TCP/IP layer can redirect traffic from one subdomain to another, resulting in a valid TLS session. This breaks the authentication of TLS and cross- protocol attacks may be possible where the behavior of one protocol service may compromise the other at the application layer. (CVE-2021-3618)

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 nginx packages.
