Security Bulletin
This security bulletin contains information about 2 vulnerabilities.
1) Heap-based buffer overflow
EUVDB-ID: #VU78506
Risk: Medium
CVSSv4.0: 6.6 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:P/U:Green]
CVE-ID: CVE-2022-24834
CWE-ID:
CWE-122 - Heap-based Buffer Overflow
Exploit availability: Yes
DescriptionThe 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.
MitigationInstall updates from vendor's repository.

2) Heap-based buffer overflow
EUVDB-ID: #VU78507
Risk: Low
CVSSv4.0: 5.9 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear]
CVE-ID: CVE-2023-36824
CWE-ID:
CWE-122 - Heap-based Buffer Overflow
Exploit availability: No
DescriptionThe 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.
