Synopsis
Multiple vulnerabilities have been found in nginx, the worst of
which may allow execution of arbitrary code.
2.
Impact Information
Background
nginx is a robust, small, and high performance HTTP and reverse proxy
server.
Description
Multiple vulnerabilities have been found in nginx:
- The TLS protocol does not properly handle session renegotiation
requests (CVE-2009-3555).
- The "ngx_http_process_request_headers()" function in ngx_http_parse.c
could cause a NULL pointer dereference (CVE-2009-3896).
- nginx does not properly sanitize user input for the the WebDAV COPY
or MOVE methods (CVE-2009-3898).
- The "ngx_resolver_copy()" function in ngx_resolver.c contains a
boundary error which could cause a heap-based buffer overflow
(CVE-2011-4315).
- nginx does not properly parse HTTP header responses which could
expose sensitive information (CVE-2012-1180).
Impact
A remote attacker could possibly execute arbitrary code with the
privileges of the nginx process, cause a Denial of Service condition,
create or overwrite arbitrary files, or obtain sensitive information.
3.
Resolution Information
Workaround
There is no known workaround at this time.
Resolution
All nginx users should upgrade to the latest version:
Code Listing 3.1: Resolution |
# emerge --sync
# emerge --ask --oneshot --verbose ">=www-servers/nginx-1.0.14"
|
