An attacker could possibly use this issue to trigger an integer overflow, which might cause Redis to allocate impossible amounts of memory, resulting in a denial of service via an application crash. (CVE-2022-35977) Tom Levy discovered that Redis incorrectly handled crafted string matching patterns. An attacker could possibly use this issue to cause Redis to hang, resulting in a denial of service. (CVE-2022-36021) Yupeng Yang discovered that Redis incorrectly handled specially crafted commands. An attacker could possibly use this issue to trigger an integer overflow, resulting in a denial of service via an application crash. (CVE-2023-25155) It was discovered that Redis incorrectly handled a specially crafted command.
