The remote Fedora 33 host has a package installed that is affected by multiple vulnerabilities as referenced in the FEDORA-2021-8d52a8a999 advisory.

  - A flaw was found in RPM's signature check functionality when reading a package file. This flaw allows an     attacker who can convince a victim to install a seemingly verifiable package, whose signature header was     modified, to cause RPM database corruption and execute code. The highest threat from this vulnerability is     to data integrity, confidentiality, and system availability. (CVE-2021-20271)

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

The remote Fedora 32 host has a package installed that is affected by multiple vulnerabilities as referenced in the FEDORA-2021-662680e477 advisory.

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

  - The RPM Package Manager (RPM) is a powerful command     line driven package management system capable of     installing, uninstalling, verifying, querying, and     updating software packages. Each software package     consists of an archive of files along with information     about the package like its version, a description,     etc.Security Fix(es):A flaw was found in RPM's     hdrblobInit() in lib/header.c. This flaw allows an     attacker who can modify the rpmdb to cause an     out-of-bounds read. The highest threat from this     vulnerability is to system     availability.(CVE-2021-20266)A flaw was found in RPM's     signature check functionality when reading a package     file. This flaw allows an attacker who can convince a     victim to install a seemingly verifiable package, whose     signature header was modified, to cause RPM database     corruption and execute code. The highest threat from     this vulnerability is to data integrity,     confidentiality, and system     availability.(CVE-2021-20271)A flaw was found in the     RPM package in the read functionality. This flaw allows     an attacker who can convince a victim to install a     seemingly verifiable package or compromise an RPM     repository, to cause RPM database corruption. The     highest threat from this vulnerability is to data     integrity.(CVE-2021-3421)

The version of Tencent Linux installed on the remote TencentOS Server 3 host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the TSSA-2022:0007 advisory.

    Package updates are available for TencentOS Server 3 that fix the following vulnerabilities:

    CVE-2021-20266:
    A flaw was found in RPM's hdrblobInit() in lib/header.c. This flaw allows an attacker who can modify the     rpmdb to cause an out-of-bounds read. The highest threat from this vulnerability is to system     availability.

    CVE-2021-3521:
    There is a flaw in RPM's signature functionality. OpenPGP subkeys are associated with a primary key via a     binding signature.[1] RPM does not check the binding signature of subkeys prior to importing them. If an     attacker is able to add or socially engineer another party to add a malicious subkey to a legitimate     public key, RPM could wrongly trust a malicious signature. The greatest impact of this flaw is to data     integrity. 1. https://tools.ietf.org/html/rfc4880#section-5.2.1

Tenable has extracted the preceding description block directly from the Tencent Linux security advisory.
