Description

pinentry on Gentoo Linux contains a flaw that may allow a malicious user to access files with unauthorised privileges. The issue is present because pinentry is installed as SGID root. This may result in a loss of confidentiality and/or integrity.

Classification

Location: Local Access Required
Attack Type: Misconfiguration
Impact: Loss of Confidentiality, Loss of Integrity
Exploit: Exploit Unknown
Disclosure: OSVDB Verified, Vendor Verified

Technical

The program 'pinentry' is not SGID root by default and can not be leveraged for additional privileges as a result of a default installation. This vulnerability only manifests because the installation process on Gentoo Linux incorrectly sets the SGID bit.

Solution

Gentoo users need to upgrade to version 0.7.2-r2 or higher, as it has been reported to fix this vulnerability. An upgrade is required as there are no known workarounds.
