SynopsisThe remote Gentoo host is missing one or more security-related patches.
DescriptionThe remote host is affected by the vulnerability described in GLSA-201203-22 (nginx: Multiple vulnerabilities)
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).
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.
SolutionAll nginx users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=www-servers/nginx-1.0.14'
