CVE-2015-8036

CWE-119Published: November 2, 2015· Updated: Jun 17, 2026

6.8
CVSS v3.1

Official Description

Heap-based buffer overflow in ARM mbed TLS (formerly PolarSSL) 1.3.x before 1.3.14 and 2.x before 2.1.2 allows remote SSL servers to cause a denial of service (client crash) and possibly execute arbitrary code via a long session ticket name to the session ticket extension, which is not properly handled when creating a ClientHello message to resume a session. NOTE: this identifier was SPLIT from CVE-2015-5291 per ADT3 due to different affected version ranges.

Technical Analysis

CVE-2015-8036 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.

Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.

From a weakness classification perspective (CWE-119): Buffer overflow vulnerabilities can lead to arbitrary code execution or denial of service by corrupting adjacent memory.
