Description
This security bulletin contains information about 11 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) Integer overflow (CVE-ID: CVE-2022-35977)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to integer overflow in SETRANGE and SORT/SORT_RO commands. A remote attacker can pass specially crafted input to the application, trigger an integer overflow and perform a denial of service (DoS) attack.
3) 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.
4) Integer overflow (CVE-ID: CVE-2023-22458)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to integer overflow in HRANDFIELD and ZRANDMEMBER commands. A remote attacker can pass specially crafted input to the application, trigger an integer overflow and perform a denial of service (DoS) attack.
5) 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.
6) 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.
7) 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.
8) 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.
9) Improper access control (CVE-ID: CVE-2023-41053)
The vulnerability allows a local user to gain unauthorized access to otherwise restricted functionality.
The vulnerability exists due to Redis does not correctly identify keys accessed by SORT_RO. This may grant users executing this command access to keys that are not explicitly authorized by the ACL configuration.
10) Heap-based buffer overflow (CVE-ID: CVE-2023-41056)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error when resizing memory buffers. A remote attacker can pass specially crafted data to the application, 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.
11) Race condition (CVE-ID: CVE-2023-45145)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a race condition between listen(2) and chmod(2) calls on startup. A local user can exploit the race and escalate privileges on the system.
