Description
This security bulletin contains information about 6 secuirty vulnerabilities.
1) 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.
2) Input validation error (CVE-ID: CVE-2024-31228)
The vulnerability allows a remote user to perform a denial of service (DoS) attack.
The vulnerability exists due to due to unbounded pattern matching. A remote user can pass specially crafted input to the application and perform a denial of service (DoS) attack.
3) 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.
4) Stack-based buffer overflow (CVE-ID: CVE-2024-31449)
The vulnerability allows a remote user to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error when processing untrusted input. A remote user with ability to influence data input can pass a specially crafted Lua script to the database, trigger a stack-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) Use-after-free (CVE-ID: CVE-2024-46981)
The vulnerability allows a remote user to compromise vulnerable system.
The vulnerability exists due to a use-after-free error when handling Lua script commands. A remote user can pass a specially crafted Lua script to the application and execute arbitrary code on the system..
Successful exploitation of the vulnerability may allow an attacker to compromise vulnerable system.
6) Path traversal (CVE-ID: CVE-2025-47273)
The vulnerability allows a remote attacker to compromise the affected system.
The vulnerability exists due to input validation error when processing directory traversal sequences in package_index.py. A remote attacker can trick the victim into installing a specially crafted script and overwrite arbitrary files on the system, leading to code execution.
