Oracle Solaris Third-Party Patch Update : libtasn1 (multiple_vulnerabilities_in_gnu_libtasn1)

medium Nessus Plugin ID 80678

Language:

Synopsis

The remote Solaris system is missing a security patch for third-party software.

Description

The remote Solaris system is missing necessary patches to address security updates :

 - 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. (CVE-2014-3469)

Solution

Upgrade to Solaris 11.1.21.4.1.
