nginx < 1.4.7 / 1.5.12 SPDY Heap Buffer Overflow

medium Nessus Plugin ID 73519

Language:

Synopsis

The remote web server is affected by a heap buffer overflow vulnerability.

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

Solution

Apply the patch manually or upgrade to nginx 1.4.7 / 1.5.12 or later.
