Description |
| 35 |
=========== |
| 36 |
|
| 37 |

| 38 |
shrink to 0 entries, which triggers an assert error. NOTE: this issue |
| 39 |
is due to an incorrect fix for CVE-2007-6239 (CVE-2008-1612). |
| 40 |
|
| 41 |
* An invalid version number in a HTTP request may trigger an |
| 42 |
assertion in HttpMsg.c and HttpStatusLine.c (CVE-2009-0478). |
| 43 |
|
| 44 |
