TITLE

nginx Vulnerability in which important information is obtained

DESCRIPTION

Use-after-free vulnerability in nginx before 1.0.14 and 1.1.x before 1.1.17 allows remote HTTP servers to obtain sensitive information from process memory via a crafted backend response, in conjunction with a client request. nginx is prone to an information-disclosure vulnerability. Attackers can exploit this issue to harvest sensitive information that may lead to further attacks. BUGTRAQ ID: 52578 CVE ID: CVE-2012-1180 nginx is a widely used high-performance web server. There is an information disclosure vulnerability in nginx's implementation of processing malformed HTTP responses from upstream servers. 0 nginx 1.0.9 nginx 1.0.8 nginx 1.0.10 Vendor patch: Igor Sysoev ----------- At present, the vendor has released an upgrade patch to fix this security problem, please go to the vendor's homepage to download: http ://nginx.net/. - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Gentoo Linux Security Advisory GLSA 201203-22 - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - http://security.gentoo.org/ - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Severity: High Title: nginx: Multiple vulnerabilities Date: March 28, 2012 Bugs: #293785, #293786, #293788, #389319, #408367 ID: 201203-22 - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - 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" References ========== [ 1 ] CVE-2009-3555 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2009-3555 [ 2 ] CVE-2009-3896 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2009-3896 [ 3 ] CVE-2009-3898 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2009-3898 [ 4 ] CVE-2011-4315 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2011-4315 [ 5 ] CVE-2012-1180 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2012-1180 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-201203-22.xml Concerns? ========= Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users' machines is of utmost importance to us.
