EulerOS 2.0 SP2 : nginx (EulerOS-SA-2021-2412)

critical Nessus Plugin ID 153261

Synopsis

The remote EulerOS host is missing multiple security updates.

Description

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

 - A security issue in nginx resolver was identified, which might allow an attacker who is able to forge UDP packets from the DNS server to cause 1-byte memory overwrite, resulting in worker process crash or potential other impact.(CVE-2021-23017)

 - NGINX before 1.13.6 has a buffer overflow for years that exceed four digits, as demonstrated by a file with a modification date in 1969 that causes an integer overflow (or a false modification date far in the future), when encountered by the autoindex module.(CVE-2017-20005)

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.
