* version.h (RELEASE): Set to "stable"
Please send GNU C library bug reports via <http://sourceware.org/bugzilla/>
using `glibc' in the "product" field.
\f
+Version 2.24.1
+
+Security related changes:
+
+* On ARM EABI (32-bit), generating a backtrace for execution contexts which
+ have been created with makecontext could fail to terminate due to a
+ missing .cantunwind annotation. This has been observed to lead to a hang
+ (denial of service) in some Go applications compiled with gccgo. Reported
+ by Andreas Schwab. (CVE-2016-6323)
+
+* The DNS stub resolver functions would crash due to a NULL pointer
+ dereference when processing a query with a valid DNS question type which
+ was used internally in the implementation. The stub resolver now uses a
+ question type which is outside the range of valid question type values.
+ (CVE-2015-5180)
+
+The following bugs are resolved with this release:
+
+ [21289] Fix symbol redirect for fts_set
