CWE-20  (opens in a new tab)

How to fix?

Upgrade Debian:8 polarssl to version 1.2.8-1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream polarssl package and not the polarssl package as distributed by Debian. See How to fix? for Debian:8 relevant fixed versions and status.

The x509parse_crt function in x509.h in PolarSSL 1.1.x before 1.1.7 and 1.2.x before 1.2.8 does not properly parse certificate messages during the SSL/TLS handshake, which allows remote attackers to cause a denial of service (infinite loop and CPU consumption) via a certificate message that contains a PEM encoded certificate.
