Synopsis ========
Multiple vulnerabilities have been found in nginx, the worst of which may allow execution of arbitrary code.
Background ==========
nginx is a robust, small, and high performance HTTP and reverse proxy server.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 www-servers/nginx < 1.0.14 >= 1.0.14
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.
Workaround ==========
There is no known workaround at this time.
Resolution ==========
All nginx users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=www-servers/nginx-1.0.14"
