All supported architectures
A buffer overflow vulnerability in nginx could result in the
execution of arbitrary code.
nginx is a robust, small, and high performance HTTP and reverse proxy
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:
Code Listing 3.1: Resolution
# emerge --sync
# emerge --ask --oneshot --verbose ">=www-servers/nginx-1.0.15"
