c561ce49-eabc-11eb-9c3f-0800270512f4redis -- Integer overflow issues with BITFIELD command on 32-bit systems

Huang Zhw reports:

On 32-bit versions, Redis BITFIELD command is vulnerable to integer overflow that can potentially be exploited to corrupt the heap, leak arbitrary heap contents or trigger remote code execution. The vulnerability involves constructing specially crafted bit commands which overflow the bit offset.

This problem only affects 32-bit versions of Redis.

838fa84a-0e25-11e5-90e4-d050996490d0redis -- EVAL Lua Sandbox Escape

Ben Murphy reports:

It is possible to break out of the Lua sandbox in Redis and execute arbitrary code.

This shouldn’t pose a threat to users under the trusted Redis security model where only trusted users can connect to the database. However, in real deployments there could be databases that can be accessed by untrusted users. The main deployments that are vulnerable are developers machines, places where redis servers can be reached via SSRF attacks and cloud hosting.

fa175f30-8c75-11e6-924a-60a44ce6887bredis -- sensitive information leak through command history file

Redis team reports:

The redis-cli history file (in linenoise) is created with the default OS umask value which makes it world readable in most systems and could potentially expose authentication credentials to other users.

0e38b8f8-75dd-11eb-83f2-8c164567ca3credis -- Integer overflow on 32-bit systems

Redis Development team reports:

Redis 4.0 or newer uses a configurable limit for the maximum supported bulk input size. By default, it is 512MB which is a safe value for all platforms. If the limit is significantly increased, receiving a large request from a client may trigger several integer overflow scenarios, which would result with buffer overflow and heap corruption.
