medium Nessus Plugin ID 155323

Language:

Synopsis

The remote Oracle Linux host is missing one or more security updates.

Description

The remote Oracle Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2021-1796 advisory.

 - Rootless containers run with Podman, receive all traffic with a source IP address of 127.0.0.1 (including from remote hosts). This impacts containerized applications that trust localhost (127.0.01) connections by default and do not require authentication. This issue affects Podman 1.8.0 onwards. (CVE-2021-20199)

 - A nil pointer dereference in the golang.org/x/crypto/ssh component through v0.0.0-20201203163018-be400aefbc4c for Go allows remote attackers to cause a denial of service against SSH servers. (CVE-2020-29652)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected packages.
