Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
Format string and Denial of Service vulnerabilities have been |
| 19 |
discovered in the monkeyd HTTP server, potentially resulting in the |
| 20 |
execution of arbitrary code. |
| 21 |
|
| 22 |
Background |
| 23 |
========== |
| 24 |
|
| 25 |
monkeyd is a fast, efficient, small and easy to configure web server |
| 26 |
for Linux. |
| 27 |
|
| 28 |
Affected packages |
| 29 |
================= |

|

| 32 |
Package / Vulnerable / Unaffected |

Description |
| 37 |
=========== |
| 38 |
|
| 39 |
Tavis Ormandy of the Gentoo Linux Security Audit Team discovered a |
| 40 |
double expansion error in monkeyd, resulting in a format string |
| 41 |
vulnerability. Ciaran McCreesh of Gentoo Linux discovered a Denial of |
| 42 |
Service vulnerability, a syntax error caused monkeyd to zero out |
| 43 |
unallocated memory should a zero byte file be requested. |
| 44 |
|
| 45 |
Impact |
| 46 |
====== |
| 47 |
|
| 48 |
The format string vulnerability could allow an attacker to send a |
| 49 |
specially crafted request to the monkeyd server, resulting in the |
| 50 |
execution of arbitrary code with the permissions of the user running |
| 51 |
monkeyd. The DoS vulnerability could allow an attacker to disrupt the |
| 52 |
operation of the web server, should a zero byte file be accessible. |
| 53 |
|
| 54 |
Workaround |
| 55 |
========== |
| 56 |
|
| 57 |
There is no known workaround at this time. |
| 58 |
|
| 59 |
Resolution |
| 60 |
========== |
| 61 |
|
| 62 |
All monkeyd users should upgrade to the latest version: |
| 63 |
|
| 64 |
# emerge --sync |
| 65 |
# emerge --ask --oneshot --verbose ">=www-servers/monkeyd-0.9.1" |
| 66 |
