Synopsis :

The remote Gentoo host is missing one or more security-related
patches.

Description :

The 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).

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.

Solution :

All nginx users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose '>=www-servers/nginx-1.0.14'

Risk factor :

Medium / CVSS Base Score : 5.8
(CVSS2#AV:N/AC:M/Au:N/C:N/I:P/A:P)
CVSS Temporal Score : 4.5
(CVSS2#E:POC/RL:OF/RC:ND)
