Synopsis

Multiple vulnerabilities have been found in mbed TLS, the worst of which could lead to the remote execution of arbitrary code.

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.

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
net-libs/mbedtls	< 2.4.2	>= 2.4.2	All supported architectures

Description

Impact

A remote attacker could possibly execute arbitrary code with the privileges of the process, or cause a Denial of Service condition.

Workaround

There is no known workaround at this time.

Resolution

All mbed TLS users should upgrade to the latest version:
