The remote Scientific Linux host is missing one or more security
It was found that GnuTLS did not check activation and expiration dates
of CA certificates. This could cause an application using GnuTLS to
incorrectly accept a certificate as valid when its issuing CA is
already expired. (CVE-2014-8155)
It was found that GnuTLS did not verify whether a hashing algorithm
listed in a signature matched the hashing algorithm listed in the
certificate. An attacker could create a certificate that used a
different hashing algorithm than it claimed, possibly causing GnuTLS
to use an insecure, disallowed hashing algorithm during certificate
It was discovered that GnuTLS did not check if all sections of X.509
certificates indicate the same signature algorithm. This flaw, in
combination with a different flaw, could possibly lead to a bypass of
the certificate signature check. (CVE-2015-0294)
The CVE-2014-8155 issue was discovered by Marcel Kolaja of Red Hat.
The CVE-2015-0282 and CVE-2015-0294 issues were discovered by Nikos
Mavrogiannopoulos of the Red Hat Security Technologies Team.
This update also fixes the following bug :
- Previously, under certain circumstances, the certtool
utility could generate X.509 certificates which
contained a negative modulus. Consequently, such
certificates could have interoperation problems with the
software using them. The bug has been fixed, and
certtool no longer generates X.509 certificates
containing a negative modulus.
