(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 privileges 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."
