(CVE-2014-3466) - Multiple unspecified vulnerabilities in the DER decoder in GNU Libtasn1 before 3.6, as used in GnutTLS, allow remote attackers to cause a denial of service (out-of-bounds read) via a crafted ASN.1 data. (CVE-2014-3467) - The asn1_get_bit_der function in GNU Libtasn1 before 3.6 does not properly report an error when a negative bit length is identified, which allows context-dependent attackers to cause out-of-bounds access via crafted ASN.1 data. (CVE-2014-3468) - The (1) asn1_read_value_type and (2) asn1_read_value functions in GNU Libtasn1 before 3.6 allows context-dependent attackers to cause a denial of service (NULL pointer dereference and crash) via a NULL value in an ivalue argument.

The gnutls packages also include the libtasn1 library, which provides Abstract Syntax Notation One (ASN.1) parsing and structures management, and Distinguished Encoding Rules (DER) encoding and decoding functions. A flaw was found in the way GnuTLS parsed session IDs from ServerHello messages of the TLS/SSL handshake. A malicious server could use this flaw to send an excessively long session ID value, which would trigger a buffer overflow in a connecting TLS/SSL client application using GnuTLS, causing the client application to crash or, possibly, execute arbitrary code. (CVE-2014-3466) It was discovered that the asn1_get_bit_der() function of the libtasn1 library incorrectly reported the length of ASN.1-encoded data. Specially crafted ASN.1 input could cause an application using libtasn1 to perform an out-of-bounds access operation, causing the application to crash or, possibly, execute arbitrary code. (CVE-2014-3468) Multiple incorrect buffer boundary check issues were discovered in libtasn1. Specially crafted ASN.1 input could cause an application using libtasn1 to crash. (CVE-2014-3467) Multiple NULL pointer dereference flaws were found in libtasn1 last seen 2020-06-01 modified 2020-06-02 plugin id 74309 published 2014-06-05 reporter This script is Copyright (C) 2014-2020 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/74309 title CentOS 5 : gnutls (CESA-2014:0594) NASL family Red Hat Local Security Checks NASL id REDHAT-RHSA-2014-0594.NASL description Updated gnutls packages that fix multiple security issues are now available for Red Hat Enterprise Linux 5. The Red Hat Security Response Team has rated this update as having Important security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section. The GnuTLS library provides support for cryptographic algorithms and for protocols such as Transport Layer Security (TLS).
