| Vetor | AV:N/AC:L/Au:N/C:N/I:N/A:C |
Name of the Vulnerable Software and Affected Versions
nginx versions 1.10.0 through 1.10.1
nginx versions 1.11.x before 1.11.1
Description
The issue is related to a NULL pointer dereference in the
os/unix/ngx files.c component of the nginx platform. This can be exploited by a remote attacker to cause a denial of service, resulting in a worker process crash. The exploitation involves writing a client request body to a temporary file using a crafted request.Recommendations
For nginx versions 1.10.0 through 1.10.1, update to version 1.10.1 or later.
For nginx versions 1.11.x before 1.11.1, update to version 1.11.1 or later.
As a temporary workaround, consider restricting access to the
os/unix/ngx files.c component to minimize the risk of exploitation.Correção
