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.
