Gentoo Linux Security Advisory

Title: nginx: User-assisted execution of arbitrary code (GLSA 201206-07)
Severity: normal
Exploitable: remote
Date: June 21, 2012
Bug(s): #411751
ID: 201206-07

Synopsis

A buffer overflow vulnerability in nginx could result in the
execution of arbitrary code.


Background

nginx is a robust, small, and high performance HTTP and reverse proxy
server.


Affected Packages

Package: www-servers/nginx
Vulnerable: < 1.0.15
Unaffected: >= 1.0.15
Architectures: All supported architectures


Description

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.


Impact

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.


Workaround

There is no known workaround at this time.

Resolution

All nginx users should upgrade to the latest version:
Code:
# emerge --sync
      # emerge --ask --oneshot --verbose ">=www-servers/nginx-1.0.15"
