mbed TLS: Multiple vulnerabilites — GLSA 201804-19

Multiple vulnerabilities have been found in mbed TLS, the worst of which could allow remote attackers to execute arbitrary code.

Affected packages

Package	net-libs/mbedtls on all architectures
Affected versions	< 2.7.2
Unaffected versions	>= 2.7.2

Background

mbed TLS (previously PolarSSL) is an “easy to understand, use, integrate and expand” implementation of the TLS and SSL protocols and the respective cryptographic algorithms and support code required.
