Gentoo: GLSA 201203-22 High Risk of Code Execution in nginx

gentoo
Calendar Grey March 28, 2012
Dist Gentoo Esm H88
Numerous security flaws detected in nginx may permit remote arbitrary code execution. Promptly recommended to upgrade.
Multiple vulnerabilities have been found in nginx, the worst of which may allow execution of arbitrary code.

Summary

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).
