CVSS v2.0
5.0
Média
| Vetor | AV:N/AC:L/Au:N/C:N/I:N/A:P |
Name of the Vulnerable Software and Affected Versions
OpenSSL versions 1.0.2 through 1.0.2a (excluding 1.0.2a)
Description
The issue is related to the dtls1 listen function in OpenSSL, which does not properly isolate state information of independent data streams. This can be exploited by a remote attacker to cause a denial of service via crafted DTLS traffic. The attacker can generate DTLS traffic to cause the application to crash due to incorrect pointer dereferences.
Recommendations
For OpenSSL versions 1.0.2 through 1.0.2a (excluding 1.0.2a), update to version 1.0.2a or later to resolve the issue.
As a temporary workaround, consider restricting DTLS traffic to minimize the risk of exploitation.
Correção
NULL Pointer Dereference
