CVE-2016-2180
CVSS v2.0
7.8
High
| Vector | AV:N/AC:L/Au:N/C:N/I:N/A:C |
Name of the Vulnerable Software and Affected Versions
OpenSSL versions 1.0.2h and earlier
Description
The issue is related to a denial of service caused by an out-of-bounds read and application crash. This can be triggered by a remote attacker via a crafted time-stamp file that is mishandled by the "openssl ts" command. The problem is associated with the TS OBJ print bio function in the X.509 Public Key Infrastructure Time-Stamp Protocol (TSP) implementation. Additionally, there is a mention of a missing CRL sanity check that could also lead to a denial of service.
Recommendations
For OpenSSL versions 1.0.2h and earlier, update to a version that includes the necessary patches to address the denial of service issue.
As a temporary workaround, consider restricting the use of the "openssl ts" command until a patch is available.
Avoid using crafted time-stamp files that could exploit the TS OBJ print bio function.
Fix
DoS
Out of bounds Read
