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

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.
