Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
Two vulnerabilities have been discovered in Lighttpd, each allowing for |
| 19 |
a Denial of Service. |
| 20 |
|
| 21 |
Background |
| 22 |
========== |
| 23 |
|
| 24 |
Lighttpd is a lightweight HTTP web server. |
| 25 |
|
| 26 |
Affected packages |
| 27 |
================= |
| 28 |
|
| 29 |
------------------------------------------------------------------- |
| 30 |
Package / Vulnerable / Unaffected |
| 31 |
------------------------------------------------------------------- |
| 32 |
1 www-servers/lighttpd < 1.4.14 >= 1.4.14 |
| 33 |
|
| 34 |
Description |
| 35 |
=========== |
| 36 |
|
| 37 |
Robert Jakabosky discovered an infinite loop triggered by a connection |
| 38 |
abort when Lighttpd processes carriage return and line feed sequences. |
| 39 |
Marcus Rueckert discovered a NULL pointer dereference when a server |
| 40 |
running Lighttpd tries to access a file with a mtime of 0. |
| 41 |
|
| 42 |
Impact |
| 43 |
====== |
| 44 |
|
| 45 |
A remote attacker could upload a specially crafted file to the server |
| 46 |
or send a specially crafted request and then abort the connection, |
| 47 |
possibly resulting in a crash or a Denial of Service by CPU |
| 48 |
consumption. |
| 49 |
|
| 50 |
Workaround |
| 51 |
========== |
| 52 |
|
| 53 |
There is no known workaround at this time. |
| 54 |
|
| 55 |
Resolution |
| 56 |
========== |
| 57 |
|
| 58 |
All Lighttpd users should upgrade to the latest version: |
| 59 |
|
| 60 |
# emerge --sync |
| 61 |
# emerge --ask --oneshot --verbose ">=www-servers/lighttpd-1.4.14" |
| 62 |
|
