CVE ID : CVE-2008-4394
CWE ID : CWE-426
Rated as : Low Risk 
Remotely Exploitable : No
Locally Exploitable : Yes
Release Date : 2008-10-13
|
A vulnerability has been identified in Gentoo, which could be exploited by local attackers to potentially obtain elevated privileges. This issue is caused by an error in several ebuilds (e.g. "sys-apps/portage", "net-mail/fetchmail" or "app-editors/leo") that execute Python using "python -c", which includes the current working directory in Python's module search path, which could be exploited by malicious users to execute arbitrary code by tricking a user into running a vulnerable application in a directory containing a specially crafted module.
Affected Products
sys-apps/portage versions prior to 2.1.4.5
Solution
Upgrade the affected packages :
# cd /root
# emerge --sync
# emerge --ask --oneshot --verbose " >=sys-apps/portage-2.1.4.5"
