A buffer overflow vulnerability in nginx could result in the execution of arbitrary code.
|Package||www-servers/nginx on all architectures|
|Affected versions||< 1.0.15|
|Unaffected versions||>= 1.0.15|
nginx is a robust, small, and high performance HTTP and reverse proxy server.
An error in ngx_http_mp4_module.c could cause a buffer overflow.
NOTE: nginx must have been emerged with USE="nginx_modules_http_mp4" in order to be affected by this vulnerability.
A remote attacker could entice a user to place a specially crafted MP4 file on the nginx server, possibly resulting in execution of arbitrary code with the privileges of the process or a Denial of Service condition.
There is no known workaround at this time.
All nginx users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=www-servers/nginx-1.0.15"
