Name of the Vulnerable Software and Affected Versions PolarSSL versions 1.x through 1.2.16 ARM mbed TLS (formerly PolarSSL) versions 1.3.x through 1.3.13 ARM mbed TLS (formerly PolarSSL) versions 2.x through 2.1.1

Description A heap-based buffer overflow issue exists, allowing remote SSL servers to cause a denial of service (client crash) and possibly execute arbitrary code. This occurs when a long hostname is sent to the server name indication (SNI) extension, which is not properly handled when creating a ClientHello message.

Recommendations For PolarSSL versions 1.x through 1.2.16, update to version 1.2.17 or later. For ARM mbed TLS (formerly PolarSSL) versions 1.3.x through 1.3.13, update to version 1.3.14 or later. For ARM mbed TLS (formerly PolarSSL) versions 2.x through 2.1.1, update to version 2.1.2 or later.
