+Version 2.20.1
+
+* The following bugs are resolved with this release:
+
+ 16617, 17266, 17370, 17371, 17460, 17485, 17555, 17625, 17630.
+
+* CVE-2104-7817 The wordexp function could ignore the WRDE_NOCMD flag
+ under certain input conditions resulting in the execution of a shell for
+ command substitution when the applicaiton did not request it. The
+ implementation now checks WRDE_NOCMD immediately before executing the
+ shell and returns the error WRDE_CMDSUB as expected.
+
+* CVE-2012-3406 printf-style functions could run into a stack overflow when
+ processing format strings with a large number of format specifiers.
+
+* CVE-2014-9402 The nss_dns implementation of getnetbyname could run into an
+ infinite loopif the DNS response contained a PTR record of an unexpected
+ format.

Version 2.20
