Summary

CVE-2014-0160 is a high-severity Out-of-bounds Read (CWE-125) vulnerability in Mitel Micollab. Its CVSS base score is 7.5 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Data Obfuscation (T1001); ranked in the top 0.0% of CVEs by exploit likelihood; CISA has added it to the Known Exploited Vulnerabilities catalog; a public proof-of-concept is referenced.

Deeper analysis AI-assisted summary

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

The vulnerability CVE-2014-0160 is a buffer over-read (CWE-125) in the TLS and DTLS implementations of OpenSSL versions 1.0.1 through 1.0.1f. It stems from improper handling of Heartbeat Extension packets in the files d1_both.c and t1_lib.c, which fails to validate the length of incoming packets before reading from process memory.

Remote attackers with network access can exploit the flaw by sending specially crafted Heartbeat requests, triggering an out-of-bounds read that discloses up to 64 KB of sensitive data such as private keys, session cookies, or other process memory contents. The attack requires no authentication and can be repeated to increase the volume of leaked data, as reflected in the CVSS 7.5 score emphasizing high confidentiality impact without affecting integrity or availability.

Advisories and patches referenced in the provided URLs, including the OpenSSL git commit 96db9023b881d7cd9f379b0c154650d6c108e9a3, indicate that the issue is resolved by upgrading to OpenSSL 1.0.1g, with distribution-specific guidance such as MGASA-2014-0165 recommending immediate updates to the patched package.

Vulnerability Data

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…
