redict vulnerability
Details

USN-7824-1 fixed several vulnerabilities in Redis. This update provides the corresponding update for Redict - a fork of Redis.

Original advisory details:

Benny Isaacs, Nir Brakha, and Sagi Tzadik discovered that Redis incorrectly handled memory when running Lua scripts. An authenticated attacker could use this vulnerability to trigger a use-after-free condition, and potentially achieve remote code execution on the Redis server.
