Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
Several security vulnerabilites have been fixed in the latest release |
| 19 |
of Apache 1.3. |
| 20 |
|
| 21 |
Background |
| 22 |
========== |
| 23 |
|
| 24 |
The Apache HTTP Server Project is an effort to develop and maintain an |
| 25 |
open-source HTTP server for modern operating systems. The goal of this |
| 26 |
project is to provide a secure, efficient and extensible server that |
| 27 |
provides services in tune with the current HTTP standards. |
| 28 |
|
| 29 |
Affected packages |
| 30 |
================= |
| 31 |
|
| 32 |
------------------------------------------------------------------- |
| 33 |
Package / Vulnerable / Unaffected |
| 34 |
------------------------------------------------------------------- |
| 35 |
1 net-www/apache < 1.3.31 >= 1.3.31 |
| 36 |
|
| 37 |
Description |
| 38 |
=========== |
| 39 |
|
| 40 |
On 64-bit big-endian platforms, mod_access does not properly parse |
| 41 |
Allow/Deny rules using IP addresses without a netmask which could |
| 42 |
result in failure to match certain IP addresses. |
| 43 |
|
| 44 |
Terminal escape sequences are not filtered from error logs. This could |
| 45 |
be used by an attacker to insert escape sequences into a terminal |
| 46 |
emulater vulnerable to escape sequences. |
| 47 |
|
| 48 |
mod_digest does not properly verify the nonce of a client response by |
| 49 |
using a AuthNonce secret. This could permit an attacker to replay the |
| 50 |
response of another website. This does not affect mod_auth_digest. |
| 51 |
|
| 52 |
On certain platforms there is a starvation issue where listening |
| 53 |
sockets fails to handle short-lived connection on a rarely-accessed |
| 54 |
listening socket. This causes the child to hold the accept mutex and |
| 55 |
block out new connections until another connection arrives on the same |
| 56 |
rarely-accessed listening socket thus leading to a denial of service. |
| 57 |
|
| 58 |
Impact |
| 59 |
====== |
| 60 |
|
| 61 |
These vulnerabilities could lead to attackers bypassing intended access |
| 62 |
restrictions, denial of service, and possibly execution of arbitrary |
| 63 |
code. |
| 64 |
|
| 65 |
Workaround |
| 66 |
========== |
| 67 |
|
| 68 |
There is no known workaround at this time. |
| 69 |
|
| 70 |
Resolution |
| 71 |
========== |
| 72 |
|
| 73 |
All users should upgrade to the latest stable version of Apache 1.3. |
| 74 |

# emerge -pv ">=net-www/apache-1.3.31" |
