Title:	mbed TLS: Multiple vulnerabilites
Date:	04/22/2018
Bugs:	#647800
ID:	201804-19

Synopsis

Multiple vulnerabilities have been found in mbed TLS, the worst of which could allow remote attackers to execute 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	< 2.7.2	>= 2.7.2	All supported architectures

Description

Multiple vulnerabilities have been discovered in mbed TLS. Please review the CVE identifiers referenced below for details.

Impact

A remote attacker, through multiple vectors, 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:

      # emerge --sync
      # emerge --ask --oneshot --verbose ">=net-libs/mbedtls-2.7.2"
