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.
Multiple vulnerabilities have been discovered in mbed TLS. Please review the CVE identifiers referenced below for details.
A remote attacker, through multiple vectors, could possibly execute arbitrary code with the privileges of the process or cause a Denial of Service condition.
There is no known workaround at this time.
All mbed TLS users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=net-libs/mbedtls-2.7.2"
