GLSA-200601-01 : pinentry: Local privilege escalation
Medium Nessus Plugin ID 20411
SynopsisThe remote Gentoo host is missing one or more security-related patches.
DescriptionThe 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 privileges of group ID 0.
A user of pinentry could potentially read and overwrite files with a group ID of 0.
There is no known workaround at this time.
SolutionAll pinentry users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=app-crypt/pinentry-0.7.2-r2'
