Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
Several bugs exist in the Heimdal ftp daemon which could allow a remote |
| 19 |
attacker to gain root privileges. |
| 20 |
|
| 21 |
Background |
| 22 |
========== |
| 23 |
|
| 24 |

Description |
| 35 |
=========== |
| 36 |
|
| 37 |
Przemyslaw Frasunek discovered several flaws in lukemftpd, which also |
| 38 |
apply to Heimdal ftpd's out-of-band signal handling code. |
| 39 |
|
| 40 |
Additionally, a potential vulnerability that could lead to Denial of |
| 41 |
Service by the Key Distribution Center (KDC) has been fixed in this |
| 42 |
version. |
| 43 |
|
| 44 |
Impact |
| 45 |
====== |
| 46 |
|
| 47 |
A remote attacker could be able to run arbitrary code with escalated |
| 48 |
privileges, which can result in a total compromise of the server. |
| 49 |
|
| 50 |
Workaround |
| 51 |
========== |
| 52 |
|
| 53 |
There is no known workaround at this time. |
| 54 |
|
| 55 |
Resolution |
| 56 |
========== |
| 57 |
|
| 58 |
All Heimdal users should upgrade to the latest version: |
| 59 |
|
| 60 |
# emerge sync |
| 61 |
|
| 62 |
# emerge -pv ">=app-crypt/heimdal-0.6.3" |
| 63 |
# emerge ">=app-crypt/heimdal-0.6.3" |
| 64 |
