An attacker could possibly escalate privileges by owning system |
| 50 |
binaries in trusted locations, cause a Denial of Service condition by |
| 51 |
manipulating the PID file from jabberd2 services, bypass security via |
| 52 |
SASL ANONYMOUS connections or have other unspecified impacts. |

Resolution |
| 60 |
========== |
| 61 |
|
| 62 |
Gentoo has discontinued support for JabberD 2.x and recommends that |
| 63 |
users unmerge the package: |
| 64 |
|
| 65 |
# emerge --unmerge "net-im/jabberd2" |
| 66 |
|
| 67 |
As an alternative, users may want to upgrade their systems to use |
| 68 |
net-im/prosody instead of net-im/jabberd2. |
