-Subject: GNU Libtasn1 2.12 released
-<#part sign=pgpmime>
-GNU Libtasn1 is a standalone library written in C for manipulating ASN.1
-objects including DER/BER encoding/decoding.  GNU Libtasn1 is used by
-GnuTLS to handle X.509 structures and by GNU Shishi to handle Kerberos
-V5 structures.
-
-* Noteworthy changes in release 2.12 (2012-03-19) [stable]
-- Cleanup license headers.
-- build: Update gnulib files.
-- Corrected DER decoding issue (reported by Matthew Hall).
-  Added self check to detect the problem, see tests/Test_overflow.c.
-  This problem can lead to at least remotely triggered crashes, see
-  further analysis on the libtasn1 mailing list.
