Impact |
| 46 |
====== |
| 47 |
|
| 48 |
A remote attacker could entice a user to process a specially crafted |
| 49 |
file in an application linked against libxslt, possibly resulting in a |
| 50 |
Denial of Service condition. |
| 51 |
|
| 52 |
Workaround |
| 53 |
========== |
| 54 |
|
| 55 |
There is no known workaround at this time. |
| 56 |
|
| 57 |
Resolution |
| 58 |
========== |
| 59 |
|
| 60 |
All libxslt users should upgrade to the latest version: |
| 61 |
|
| 62 |
# emerge --sync |
| 63 |
# emerge --ask --oneshot --verbose ">=dev-libs/libxslt-1.1.28" |
| 64 |
|
| 65 |
Packages which depend on this library may need to be recompiled. Tools |
| 66 |
such as revdep-rebuild may assist in identifying some of these |
| 67 |
packages. |
