CWE-200Published: December 15, 2007· Updated: Jun 16, 2026
2.1
CVSS v3.1
Official Description
etc-update in Portage before 2.1.3.11 on Gentoo Linux relies on the umask to set permissions for the merge file, often resulting in permissions weaker than those of the original files, which might allow local users to obtain sensitive information by reading the merge file.
Technical Analysis
CVE-2007-6249 requires local access, meaning attackers must already have a foothold on the target system.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
From a weakness classification perspective (CWE-200): Information exposure vulnerabilities leak sensitive data to unauthorized actors.
