OESA-2021-1163 (CVE-2021-20271)

Vulnerability from osv_openeuler – Published: 2021-05-06 11:04 – Updated: 2026-08-06 11:04 – Source website

Summary

rpm security update

Details

The RPM Package Manager (RPM) is a powerful package management system capability as below -building computer software from source into easily distributable packages -installing, updating and uninstalling packaged software -querying detailed information about the packaged software, whether installed or not -verifying integrity of packaged software and resulting software installation

Security Fix(es):

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)

Severity

7.0 (High)
