Описание

Redis is an in-memory database that persists on disk. A vulnerability involving out-of-bounds read and integer overflow to buffer overflow exists starting with version 2.2 and prior to versions 5.0.13, 6.0.15, and 6.2.5. On 32-bit systems, Redis *BIT* command are 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 changing the default proto-max-bulk-len configuration parameter to a very large value and constructing specially crafted commands bit commands. This problem only affects Redis on 32-bit platforms, or compiled as a 32-bit binary. Redis versions 5.0.3m 6.0.15, and 6.2.5 contain patches for this issue. An additional workaround to mitigate the problem without patching the redis-serverexecutable is to prevent users from modifying theproto-max-bulk-len` configuration parameter. This can be done using ACL to restrict unprivileged users from using the CONFIG SET command.

A flaw was found in Redis. Issuing the BITFIELD command on a 32-bit version of Redis may result in an integer wrap around allowing an attacker to crash the service or perform remote code execution. The highest threat from this vulnerability is to the data confidentiality, integrity, and service availability.

Отчет

This does not affect Redis 5 and Redis 6 packages shipped on Red Hat Enterprise Linux 7 and Red Hat Enterprise Linux 8, as they are 64-bit packages and the issue only affects 32-bit.
