Nginx < 1.4.7 SPDY Heap Buffer Overflow

critical Web App Scanning Plugin ID 98956

Synopsis

Nginx < 1.4.7 SPDY Heap Buffer Overflow

Description

According to the self-reported version in the server response header, the installed 1.3.x version of nginx is 1.3.15 or higher, or 1.4.x prior to 1.4.7, or 1.5.x prior to 1.5.12. It is, therefore, affected by a heap buffer overflow vulnerability.

A flaw exists with the SPDY protocol implementation where user input is not properly validated. This could allow a remote attacker to cause a heap-based buffer overflow, causing a denial of service or potential arbitrary code execution.

Note that the scanner has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade to nginx 1.4.7 or later.
