The patch for the Redis bug has been released to fix a potentially exploitable issue related to the MsgPack library and its variadic function in Lua, which could lead to stack overflow and remote code execution if not properly checked. The bug is considered low-risk as it would require very specific scenarios and untrusted user inputs to be exploited. However, applying the patch ensures that the fix is available for all users, including those using Redis Enterprise offerings. Users are advised to ensure their Redis instances are not unrestrictedly open to the internet and upgrade to the latest version of Redis if necessary. The patch has also been implemented in other Lua libraries to address similar issues.
