Description Jan Lieskovsky 2013-05-07 13:31:18 UTC
A stack-based buffer overflow flaw was found in the way Nginx, a high performance web server and reverse proxy server for HTTP, SMTP, POP3, and IMAP protocols, performed processing of certain chunked transfer encoding HTTP requests. A remote attacker could provide a HTTP request with specially-crafted size or length values of the chunked packet that, when processed would lead to nginx daemon / service crash.

Comment 1 Jan Lieskovsky 2013-05-07 13:33:45 UTC
This issue did NOT affect the versions of the nginx package, as shipped with Fedora release of 17, 18, Fedora EPEL-5, and Fedora EPEL-6 (as they did not contain support for HTTP chunked transfer encoding yet).

Comment 2 Jan Lieskovsky 2013-05-07 13:34:19 UTC
Created nginx tracking bugs for this issue

Affects: fedora-rawhide [bug 960606]
