CVE-2016-6306

CVSS v2.0

7.1

High

VectorAV:N/AC:M/Au:N/C:N/I:N/A:C
Name of the Vulnerable Software and Affected Versions OpenSSL versions prior to 1.0.1u OpenSSL versions prior to 1.0.2i
Description The issue is related to a buffer over-read in the certificate parser of OpenSSL, which could allow remote attackers to cause a denial of service. This is achieved through crafted certificate operations, and it is related to the files s3 clnt.c and s3 srvr.c. The vulnerability can be exploited by remote attackers.
Recommendations For OpenSSL versions prior to 1.0.1u, update to version 1.0.1u or later. For OpenSSL versions prior to 1.0.2i, update to version 1.0.2i or later. As a temporary workaround, consider restricting the use of crafted certificate operations until a patch is available.
