Impact |
| 50 |
====== |
| 51 |
|
| 52 |
A remote attacker could possibly execute arbitrary code by enticing a |
| 53 |
user or automated system to open a file with a long filename or via |
| 54 |
unspecified vectors. It is also possible to trick a user into deleting |
| 55 |
or overwriting files. |
| 56 |
|
| 57 |
Workaround |
| 58 |
========== |
| 59 |
|
| 60 |
There is no known workaround at this time. |
| 61 |
|
| 62 |
Resolution |
| 63 |
========== |
| 64 |
|
| 65 |
All JHead users should upgrade to the latest version: |
| 66 |
|
| 67 |
# emerge --sync |
| 68 |
# emerge --ask --oneshot --verbose ">=media-gfx/jhead-2.84-r1" |
| 69 |
