Redis 2.8.23 -> 2.8.24 is a small bugfix release:

    --[ Redis 2.8.24 ] Release date: 18 Dec 2015

    Upgrade urgency: MODERATE. We fixed a crash that happens very rarely, so
                     updating does not hurt, but most users are unlikely to
                     experience this condition because it requires some odd
                     timing.

    * [FIX] lua_struct.c/getnum security issue fixed. (Luca Bruno discovered it,
            patched by Sun He and Chris Lamb)
    * [FIX] Fix a race condition in processCommand() because of interactions
            with freeMemoryIfNeeded(). Details in issue #2948 and especially
            in the commit message d999f5a. (Race found analytically by
            Oran Agra, patch by Salvatore Sanfilippo)

    * [NEW] Log offending memory access address on SIGSEGV/SIGBUS (Salvatore
            Sanfilippo)
