Description
This security bulletin contains information about 6 secuirty vulnerabilities.
1) Heap-based buffer overflow (CVE-ID: CVE-2022-24834)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error within the cjson and cmsgpack libraries. A remote attacker can trick the victim into using a specially crafted Lua script to trigger a heap-based buffer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
2) Resource exhaustion (CVE-ID: CVE-2022-36021)
The vulnerability allows a remote user to perform a denial of service (DoS) attack.
The vulnerability exists due to application does not properly control consumption of internal resources when matching commands (like SCAN or KEYS) with a specially crafted pattern. A remote user can trigger resource exhaustion and perform a denial of service (DoS) attack.
3) Integer overflow (CVE-ID: CVE-2023-25155)
The vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to integer overflow in the "SRANDMEMBER", "ZRANDMEMBER" and "HRANDFIELD" commands. A local user can pass specially crafted data to the application, trigger integer overflow and cause a denial of service condition on the target system.
4) Reachable Assertion (CVE-ID: CVE-2023-28425)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a reachable assertion when handling the MSETNX command. A remote attacker can send a specially crafted MSETNX command and perform a denial of service (DoS) attack.
5) Input validation error (CVE-ID: CVE-2023-28856)
The vulnerability allows a remote user to perform a denial of service (DoS) attack.
The vulnerability exists due to insufficient validation of user-supplied input. A remote user can use the HINCRBYFLOAT command to create an invalid hash field that will crash Redis on access.
6) Heap-based buffer overflow (CVE-ID: CVE-2023-36824)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a boundary error when extracting key names from a command and a list of arguments. A local user can execute the "COMMAND GETKEYS" or "COMMAND GETKEYSANDFLAGS" commands or execute a specially crafted command that refers to a variadic list of key names along with ACL rules that match key names to trigger a heap-based buffer overflow and execute arbitrary code on the target system.
