Synopsis:    Important: libtasn1 security update
Issue Date:  2012-03-27
CVE Numbers: CVE-2012-1569


libtasn1 is a library developed for ASN.1 (Abstract Syntax Notation One)
structures management that includes DER (Distinguished Encoding Rules)
encoding and decoding.

A flaw was found in the way libtasn1 decoded DER data. An attacker could
create carefully-crafted DER encoded input (such as an X.509 certificate)
that, when parsed by an application that uses libtasn1 (such as
applications using GnuTLS), could cause the application to crash.
(CVE-2012-1569)

Users of libtasn1 are advised to upgrade to these updated packages, which
contain a backported patch to correct this issue. For the update to take
effect, all applications linked to the libtasn1 library must be restarted,
or the system rebooted.
