GnuTLS before 2017-02-20 has an out-of-bounds write caused by an integer overflow and heap-based buffer overflow related to the cdk_pkt_read function in opencdk/read-packet.c. This issue (which is a subset of the vendor's GNUTLS-SA-2017-3 report) is fixed in 3.5.10.

The remote Redhat Enterprise Linux 5 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: Heap read overflow in read-packet.c (CVE-2017-5337)

  - The TLS protocol 1.2 and earlier, as used in Mozilla Firefox, Google Chrome, Qt, and other products, can     encrypt compressed data without properly obfuscating the length of the unencrypted data, which allows man-     in-the-middle attackers to obtain plaintext HTTP headers by observing length differences during a series     of guesses in which a string in an HTTP request potentially matches an unknown string in an HTTP header,     aka a CRIME attack. (CVE-2012-4929)

  - GnuTLS before 2.9.10 does not verify the activation and expiration dates of CA certificates, which allows     man-in-the-middle attackers to spoof servers via a certificate issued by a CA certificate that is (1) not     yet valid or (2) no longer valid. (CVE-2014-8155)

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

The remote Redhat Enterprise Linux 6 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.

  - libtasn1: asn1_get_bit_der() can return negative bit length (CVE-2014-3468)

  - gnutls: HMAC-SHA-384 vulnerable to Lucky thirteen attack due to use of wrong constant (CVE-2018-10845)

  - The asn1_get_length_der function in decoding.c in GNU Libtasn1 before 2.12, as used in GnuTLS before     3.0.16 and other products, does not properly handle certain large length values, which allows remote     attackers to cause a denial of service (heap memory corruption and application crash) or possibly have     unspecified other impact via a crafted ASN.1 structure. (CVE-2012-1569)

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

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.

An update of the gnutls package has been released.

An update for gnutls is now available for Red Hat Enterprise Linux 7.

Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.

The gnutls packages provide the GNU Transport Layer Security (GnuTLS) library, which implements cryptographic algorithms and protocols such as SSL, TLS, and DTLS.

The following packages have been upgraded to a later upstream version:
gnutls (3.3.26). (BZ#1378373)

Security Fix(es) :

* A double-free flaw was found in the way GnuTLS parsed certain X.509 certificates with Proxy Certificate Information extension. An attacker could create a specially crafted certificate which, when processed by an application compiled against GnuTLS, could cause that application to crash. (CVE-2017-5334)

* Multiple flaws were found in the way gnutls processed OpenPGP certificates. An attacker could create specially crafted OpenPGP certificates which, when parsed by gnutls, would cause it to crash.
(CVE-2017-5335, CVE-2017-5336, CVE-2017-5337, CVE-2017-7869)

* A NULL pointer dereference flaw was found in the way GnuTLS processed ClientHello messages with status_request extension. A remote attacker could use this flaw to cause an application compiled with GnuTLS to crash. (CVE-2017-7507)

* A flaw was found in the way GnuTLS validated certificates using OCSP responses. This could falsely report a certificate as valid under certain circumstances. (CVE-2016-7444)

The CVE-2017-7507 issue was discovered by Hubert Kario (Red Hat QE BaseOS Security team).
