Synopsis |
16 |
======== |
17 |
|
18 |
Multiple vulnerabilities have been found in nginx, the worst of which |
19 |
may allow execution of arbitrary code. |
20 |
|
21 |
Background |
22 |
========== |
23 |
|
24 |
nginx is a robust, small, and high performance HTTP and reverse proxy |
25 |
server. |
26 |
|
27 |
Affected packages |

Description |
36 |
=========== |
37 |
|
38 |
Multiple vulnerabilities have been found in nginx: |
39 |
|
40 |
* The TLS protocol does not properly handle session renegotiation |
41 |
requests (CVE-2009-3555). |
42 |
* The "ngx_http_process_request_headers()" function in ngx_http_parse.c |
43 |
could cause a NULL pointer dereference (CVE-2009-3896). |
44 |
* nginx does not properly sanitize user input for the the WebDAV COPY |
45 |
or MOVE methods (CVE-2009-3898). |
46 |
* The "ngx_resolver_copy()" function in ngx_resolver.c contains a |
47 |
boundary error which could cause a heap-based buffer overflow |
48 |
(CVE-2011-4315). |
49 |
* nginx does not properly parse HTTP header responses which could |
50 |
expose sensitive information (CVE-2012-1180). |
51 |
|
52 |
Impact |
53 |
====== |
54 |
|
55 |
A remote attacker could possibly execute arbitrary code with the |
56 |
privileges of the nginx process, cause a Denial of Service condition, |
57 |
create or overwrite arbitrary files, or obtain sensitive information. |
58 |
|
59 |
Workaround |
60 |
========== |
61 |
|
62 |
There is no known workaround at this time. |
63 |
|
64 |
Resolution |
65 |
========== |
66 |
|
67 |
All nginx users should upgrade to the latest version: |
68 |
|
69 |
# emerge --sync |
70 |
# emerge --ask --oneshot --verbose ">=www-servers/nginx-1.0.14" |
71 |
