Description |
| 38 |
=========== |
| 39 |
|
| 40 |
Stefan Esser discovered a vulnerability in the code of the neon library |
| 41 |
: if a malicious date string is passed to the ne_rfc1036_parse() |
| 42 |

Impact |
| 45 |
====== |
| 46 |
|
| 47 |
Depending on the application linked against libneon and when connected |
| 48 |
to a malicious WebDAV server, this vulnerability could allow execution |
| 49 |
of arbitrary code with the rights of the user running that application. |
| 50 |
|
| 51 |
Workaround |
| 52 |
========== |
| 53 |
