Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
pinentry is vulnerable to privilege escalation. |
| 19 |
|
| 20 |
Background |
| 21 |
========== |
| 22 |
|
| 23 |
pinentry is a collection of simple PIN or passphrase entry dialogs |
| 24 |
which utilize the Assuan protocol. |
| 25 |
|
| 26 |
Affected packages |
| 27 |
================= |
| 28 |
|
| 29 |
------------------------------------------------------------------- |
| 30 |
Package / Vulnerable / Unaffected |
| 31 |
------------------------------------------------------------------- |
| 32 |
1 app-crypt/pinentry < 0.7.2-r2 >= 0.7.2-r2 |
| 33 |
|
| 34 |
Description |
| 35 |
=========== |
| 36 |
|
| 37 |
Tavis Ormandy of the Gentoo Linux Security Audit Team has discovered |
| 38 |
that the pinentry ebuild incorrectly sets the permissions of the |
| 39 |
pinentry binaries upon installation, so that the sgid bit is set making |
| 40 |
them execute with the privileges of group ID 0. |
| 41 |
|
| 42 |
Impact |
| 43 |
====== |
| 44 |
|
| 45 |
A user of pinentry could potentially read and overwrite files with a |
| 46 |
group ID of 0. |
| 47 |
|
| 48 |
Workaround |
| 49 |
========== |
| 50 |
|
| 51 |
There is no known workaround at this time. |
| 52 |
|
| 53 |
Resolution |
| 54 |
========== |
| 55 |
|
| 56 |
All pinentry users should upgrade to the latest version: |
| 57 |
|
| 58 |
# emerge --sync |
| 59 |
# emerge --ask --oneshot --verbose ">=app-crypt/pinentry-0.7.2-r2" |
| 60 |
