EulerOS 2.0 SP3 : strongimcv (EulerOS-SA-2022-1767)

high Nessus Plugin ID 161598

Synopsis

The remote EulerOS host is missing a security update.

Description

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

- The in-memory certificate cache in strongSwan before 5.9.4 has a remote integer overflow upon receiving many requests with different certificates to fill the cache and later trigger the replacement of cache entries. The code attempts to select a less-often-used cache entry by means of a random number generator, but this is not done correctly. Remote code execution might be a slight possibility. (CVE-2021-41991)

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 strongimcv packages.
