The (1) TLS and (2) DTLS implementations in OpenSSL 1.0.1 before 1.0.1g do not properly handle Heartbeat Extension packets, which allows remote attackers to obtain sensitive information from process memory via crafted packets that trigger a buffer over-read, as demonstrated by reading private keys, related to d1_both.c and t1_lib.c, aka the Heartbleed bug.

Are you affected?

Enter the version you run. The result uses only the ranges stored on this record.

The check returns affected, not affected, or incomplete. It does not guess a version that is missing from the record.

How to fix CVE-2014-0160

What to do

Three questions, each answered from this record only. Confirm the vendor advisory before you patch.

Should you patch?

CVE-2014-0160 is in the CISA known-exploited catalog, due May 25, 2022. Confirm OpenSSL OpenSSL against the vendor advisory and apply that fix. The CVSS score does not change the priority.

Which versions are affected?

Compare what you have installed with intellian/v100 firmware 1.20; intellian/v60 firmware 1.15; siemens/application processing engine firmware 2.0; siemens/cp 1543-1 firmware 1.1. Apply updates per vendor instructions.

What should an analyst verify?

CWE-125: Out-of-bounds Read. EPSS 100.00%. The CISA KEV listing is the exploitation evidence. A public exploit reference is linked in Sources. That is not the same as confirmed exploitation. Use the source links for the original advisory.
