    1. Summary:
    
    Updated libtasn1 packages that fix three security issues are now available
    for Red Hat Enterprise Linux 6.
    
    The Red Hat Security Response Team has rated this update as having Moderate
    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.

    3. Description:
    
    The libtasn1 library provides Abstract Syntax Notation One (ASN.1) parsing
    and structures management, and Distinguished Encoding Rules (DER) encoding
    and decoding functions.
    
    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's
    asn1_read_value() function. Specially crafted ASN.1 input could cause an
    application using libtasn1 to crash, if the application used the
    aforementioned function in a certain way. (CVE-2014-3469)
    
    Red Hat would like to thank GnuTLS upstream for reporting these issues.
    
    All libtasn1 users are advised to upgrade to these updated packages, which
    correct these issues. For the update to take effect, all applications
    linked to the libtasn1 library must be restarted.
    
    4. Solution:
    
    Before applying this update, make sure all previously released errata
    relevant to your system have been applied.
    
    This update is available via the Red Hat Network. Details on how to use the
    Red Hat Network to apply this update are available at
    https://access.redhat.com/site/articles/11258
    
    5. Bugs fixed (https://bugzilla.redhat.com/):
    
    1102022 - CVE-2014-3467 libtasn1: multiple boundary check issues
    1102323 - CVE-2014-3468 libtasn1: asn1_get_bit_der() can return negative bit length
    1102329 - CVE-2014-3469 libtasn1: asn1_read_value_type() NULL pointer dereference
