    It was discovered that there were a number of issues in Redis, a popular
    key-value database:

     * CVE-2023-45145: On startup, Redis began listening on a Unix
       socket before adjusting its permissions to the user-provided
       configuration. If a permissive umask(2) was used, this created a
       race condition that enabled, during a short period of time,
       another process to establish an otherwise unauthorized connection.

     * CVE-2023-28856: Authenticated users could have used the
       HINCRBYFLOAT command to create an invalid hash field that would
       have crashed the Redis server on access.

     * CVE-2023-25155: Authenticated users issuing specially crafted
       SRANDMEMBER, ZRANDMEMBER, and HRANDFIELD commands can trigger an
       integer overflow, resulting in a runtime assertion and termination
       of the Redis server process.

     * CVE-2022-36021: Authenticated users can use string matching
       commands (like SCAN or KEYS) with a specially crafted pattern to
       trigger a denial-of-service attack on Redis, causing it to hang
       and consume 100% CPU time.

     * CVE-2022-24834: A specially-crafted Lua script executing in Redis
       could have triggered a heap overflow in the cjson and cmsgpack
       libraries and result in heap corruption and potentially remote
       code execution.


    For Debian 11 bullseye, these problems have been fixed in version
    5:6.0.16-1+deb11u3.

    We recommend that you upgrade your redis packages.
