CVE-2014-1492

Status Candidate

Overview

The cert_TestHostName function in lib/certdb/certdb.c in the certificate-checking implementation in Mozilla Network Security Services (NSS) before 3.16 accepts a wildcard character that is embedded in an internationalized domain name's U-label, which might allow man-in-the-middle attackers to spoof SSL servers via a crafted certificate.

Red Hat Security Advisory 2014-1246-01 - Network Security Services is a set of libraries designed to support the cross-platform development of security-enabled client and server applications. A flaw was found in the way TLS False Start was implemented in NSS. An attacker could use this flaw to potentially return unencrypted information from the server. A race condition was found in the way NSS implemented session ticket handling as specified by RFC 5077. An attacker could use this flaw to crash an application using NSS or, in rare cases, execute arbitrary code with the privileges of the user running that application.

Red Hat Security Advisory 2014-1073-01 - Network Security Services is a set of libraries designed to support the cross-platform development of security-enabled client and server applications. Applications built with NSS can support SSLv3, TLS, and other security standards. It was found that the implementation of Internationalizing Domain Names in Applications hostname matching in NSS did not follow the RFC 6125 recommendations. This could lead to certain invalid certificates with international characters to be accepted as valid. In addition, the nss, nss-util, and nss-softokn packages have been upgraded to upstream version 3.16.2, which provides a number of bug fixes and enhancements over the previous versions.

Mandriva Linux Security Advisory 2014-066
Posted Mar 20, 2014
Authored by Mandriva | Site mandriva.com

Mandriva Linux Security Advisory 2014-066 - A vulnerability has been found and corrected in mozilla NSS. In a wildcard certificate, the wildcard character should not be embedded within the U-label of an internationalized domain name. See the last bullet point in RFC 6125, Section 7.2. The updated packages have been upgraded to the latest NSPR and NSS versions which is not vulnerable to this issue. Additionally the rootcerts package has also been updated to version 1.97, which adds, removes, and distrusts several certificates.
