TITLE:
Gentoo Portage Insecure Python Module Search Path Security Issue

SECUNIA ADVISORY ID:
SA32228

VERIFY ADVISORY:
http://secunia.com/advisories/32228/

CRITICAL:
Not critical

IMPACT:
Privilege escalation

WHERE:
Local system

OPERATING SYSTEM:
Gentoo Linux 1.x
http://secunia.com/advisories/product/339/

DESCRIPTION:
Gentoo has acknowledged a security issue in portage, which can be
exploited by malicious, local users to gain escalated privileges.

The security issue is caused due to portage including the current
working directory into the module search path. This can be exploited
by placing a malicious module into a directory (e.g. "/tmp") and then
tricking the administrator into using portage to emerge certain
packages (e.g. "sys-apps/portage", "net-mail/fetchmail", or
"app-editors/leo") in the same directory.

The security issue is reported in all versions prior to 2.1.4.5.

SOLUTION:
Update to "sys-apps/portage-2.1.4.5" from trusted working directory.

PROVIDED AND/OR DISCOVERED BY:
Reported by the vendor.

ORIGINAL ADVISORY:
