Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
A vulnerability in OpenID library for Ruby at worst might allow an |
| 19 |
attacker to bypass authentication. |
| 20 |
|
| 21 |
Background |
| 22 |
========== |
| 23 |
|
| 24 |
A Ruby library for verifying and serving OpenID identities. |
| 25 |
|
| 26 |
Affected packages |
| 27 |
================= |
| 28 |
|
| 29 |
------------------------------------------------------------------- |
| 30 |
Package / Vulnerable / Unaffected |
| 31 |
------------------------------------------------------------------- |
| 32 |
1 dev-ruby/ruby-openid < 2.9.2 >= 2.9.2 |
| 33 |
|
| 34 |
Description |
| 35 |
=========== |
| 36 |
|
| 37 |
It was discovered that OpenID library for Ruby performed discovery |
| 38 |
first, and then verification. |
| 39 |
|
| 40 |
Impact |
| 41 |
====== |
| 42 |
|
| 43 |
A remote attacker could possibly change the URL used for discovery and |
| 44 |
trick the server into connecting to the URL. This server in turn could |
| 45 |
be a private server not |
| 46 |
publicly accessible. |
| 47 |
|
| 48 |
In addition, if the client that uses this library discloses connection |
| 49 |
errors, this in turn could disclose information from the private server |
| 50 |
to the attacker. |
| 51 |
|
| 52 |
Workaround |
| 53 |
========== |
| 54 |
|
| 55 |
There is no known workaround at this time. |
| 56 |
|
| 57 |
Resolution |
| 58 |
========== |
| 59 |
|
| 60 |
All ruby-openid users should upgrade to the latest version: |
| 61 |
|
| 62 |
# emerge --sync |
| 63 |
# emerge --ask --oneshot --verbose ">=dev-ruby/ruby-openid-2.9.2" |
| 64 |
