CWE-20

Description

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.

Affected configurations

• polarssl polarssl 1.1.0 • polarssl polarssl 1.1.1 • polarssl polarssl 1.1.2 • polarssl polarssl 1.1.3 • polarssl polarssl 1.1.4 • polarssl polarssl 1.1.5 • polarssl polarssl 1.1.6 • polarssl polarssl 1.2.0 • polarssl polarssl 1.2.1 • polarssl polarssl 1.2.2 • polarssl polarssl 1.2.3 • polarssl polarssl 1.2.4 • polarssl polarssl 1.2.5 • polarssl polarssl 1.2.6 • polarssl polarssl 1.2.7
