Impact |
| 50 |
====== |
| 51 |
|
| 52 |
A remote attacker could exploit these vulnerabilities by sending |
| 53 |
specially crafted packets on a network being monitored by Wireshark or |
| 54 |
by enticing a user to read a malformed packet trace file, causing a |
| 55 |
Denial of Service. |
| 56 |
|
| 57 |
Workaround |
| 58 |
========== |
| 59 |
|
| 60 |
There is no known workaround at this time. |
| 61 |
|
| 62 |
Resolution |
| 63 |
========== |
| 64 |
|
| 65 |
All Wireshark users should upgrade to the latest version: |
| 66 |
|
| 67 |
# emerge --sync |
| 68 |
# emerge --ask --oneshot --verbose ">=net-analyzer/wireshark-1.0.3" |
