Description
This security bulletin contains information about 5 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) 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.
3) 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.
4) 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.
5) 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.
