Double free vulnerability in lib/x509/x509_ext.c in GnuTLS before 3.3.14 allows remote attackers to cause a denial of service or possibly have unspecified other impact via a crafted CRL distribution point.

The remote Redhat Enterprise Linux 7 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - gnutls: certificate algorithm consistency checking issue (CVE-2015-0294)

  - gnutls: use-after-free flaw in CRL distribution points parsing (CVE-2015-3308)

  - Double free vulnerability in GnuTLS before 3.3.17 and 3.4.x before 3.4.4 allows remote attackers to cause     a denial of service via a long DistinguishedName (DN) entry in a certificate. (CVE-2015-6251)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

According to the version of the gnutls packages installed, the EulerOS installation on the remote host is affected by the following vulnerability :

  - Double free vulnerability in lib/x509/x509_ext.c in     GnuTLS before 3.3.14 allows remote attackers to cause a     denial of service or possibly have unspecified other     impact via a crafted CRL distribution     point.(CVE-2015-3308)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

It was discovered that GnuTLS incorrectly handled parsing CRL distribution points. A remote attacker could possibly use this issue to cause a denial of service, or execute arbitrary code.
