SeungHyun Lee discovered that Redis incorrectly handled specially crafted
commands. 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

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. An attacker could possibly use this issue to create an invalid
hash field, which could potentially cause Redis to crash on future access.
(CVE-2023-28856)
Alexander Aleksandrovic Klimov discovered that Redis incorrectly listened
to a Unix socket before setting proper permissions. A local attacker could
possibly use this issue to connect, bypassing intended permissions.
