Vulnerability Assessment Summary
pinentry: Local privilege escalation

Detailed Explanation for this Vulnerability Assessment
The remote host is affected by the vulnerability described in GLSA-200601-01
(pinentry: Local privilege escalation)

Tavis Ormandy of the Gentoo Linux Security Audit Team has
discovered that the pinentry ebuild incorrectly sets the permissions of
the pinentry binaries upon installation, so that the sgid bit is set
making them execute with the rights of group ID 0.

Impact

A user of pinentry could potentially read and overwrite files with
a group ID of 0.

Workaround

There is no known workaround at this time.

Solution:
All pinentry users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=app-crypt/pinentry-0.7.2-r2"

Network Security Threat Level: Medium
