SECUNIA ADVISORY ID:
SA18284

VERIFY ADVISORY:
http://secunia.com/advisories/18284/

CRITICAL:
Less critical

IMPACT:
Privilege escalation

WHERE:
Local system

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

DESCRIPTION:
Tavis Ormandy has reported a security issue in pinentry, which
potentially can be exploited by malicious, local users to perform
certain actions on a vulnerable system with escalated privileges.

The problem is that the pinentry ebuild assigns insecure permissions
for the pinentry binaries in the installation process. This may be
exploited to disclose the content of or manipulate arbitrary files
with a group ID of 0.

SOLUTION:
Update to "app-crypt/pinentry-0.7.2-r2" or later.

PROVIDED AND/OR DISCOVERED BY:
Tavis Ormandy, Gentoo Linux Security Audit Team
