Description Johan Bergström 2013-05-07 13:22:28 UTC
Greg MacManus, of iSIGHT Partners Labs, found a security problem
in several recent versions of nginx.  A stack-based buffer
overflow might occur in a worker process while handling a
specially crafted request, potentially resulting in arbitrary code
execution (CVE-2013-2028).

The problem affects nginx 1.3.9 - 1.4.0.

The problem is fixed in nginx 1.5.0, 1.4.1.

Maintainers: I have tested renaming nginx-1.4.0-r1 to nginx-1.4.1 which worked well in my setup.

CVE-2013-2070 (
  http/modules/ngx_http_proxy_module.c in nginx 1.1.4 through 1.2.8 and 1.3.0
  through 1.4.0, when proxy_pass is used with untrusted HTTP servers, allows
  remote attackers to cause a denial of service (crash) and obtain sensitive
  information from worker process memory via a crafted proxy response, a
  similar vulnerability to CVE-2013-2028.

CVE-2013-2028 (
  The ngx_http_parse_chunked function in http/ngx_http_parse.c in nginx 1.3.9
  through 1.4.0 allows remote attackers to cause a denial of service (crash)
  and execute arbitrary code via a chunked Transfer-Encoding request with a
  large chunk size, which triggers an integer signedness error and a
  stack-based buffer overflow.
