Description

This security bulletin contains information about 3 secuirty vulnerabilities.


1) Input validation error (CVE-ID: CVE-2014-3467)

The vulnerability allows a remote non-authenticated attacker to perform service disruption.

Multiple unspecified vulnerabilities in the DER decoder in GNU Libtasn1 before 3.6, as used in GnuTLS, allow remote attackers to cause a denial of service (out-of-bounds read) via crafted ASN.1 data.


2) Input validation error (CVE-ID: CVE-2014-3468)

The vulnerability allows a remote non-authenticated attacker to read and manipulate data.

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.


3) Input validation error (CVE-ID: CVE-2014-3469)

The vulnerability allows context-dependent attackers to perform a denial of service (DoS) attack.

The vulnerability exists due to insufficient validation of user-supplied input. A remote attacker can cause a denial of service (NULL pointer dereference and crash) via a NULL value in an ivalue argument.
