Multiple vulnerabilities have been found in nginx, the worst of
which may allow execution of arbitrary code.
nginx is a robust, small, and high performance HTTP and reverse proxy
Multiple vulnerabilities have been found in nginx:
- The TLS protocol does not properly handle session renegotiation
- 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
- nginx does not properly parse HTTP header responses which could
expose sensitive information (CVE-2012-1180).
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.
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-1.0.14"
