Security Bulletin
This security bulletin contains information about 5 vulnerabilities.
1) Heap-based buffer overflow
EUVDB-ID: #VU60553
Risk: Medium
CVSSv3.1: 7.7 [CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2022-24052
CWE-ID:
CWE-122 - Heap-based Buffer Overflow
Exploit availability: No
DescriptionThe vulnerability allows a remote user to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error in the storage engine when processing CONNECT requests. A remote user can send a specially crafted SQL query to the database instance, 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.
