| Vetor | AV:N/AC:L/Au:N/C:N/I:N/A:C |
Name of the Vulnerable Software and Affected Versions
OpenSSL versions 1.1.0 through 1.1.0d
Description
The issue is related to a null pointer dereference in the OpenSSL library. This can be exploited by a remote attacker to cause a denial of service. If a malicious server provides bad parameters for a DHE or ECDHE key exchange, the client may attempt to dereference a null pointer, leading to a client crash. This could be exploited in a denial of service attack.
Recommendations
For versions 1.1.0 through 1.1.0d, update to version 1.1.0d or later to resolve the issue.
As a temporary workaround, consider restricting the use of DHE or ECDHE key exchange until a patch is available.
