Security Bulletin
This security bulletin contains information about 3 vulnerabilities.
1) Integer overflow
EUVDB-ID: #VU63342
Risk: Low
CVSSv3.1: 3.4 [CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:N/A:N/E:P/RL:O/RC:C]
CVE-ID: CVE-2022-22976
CWE-ID:
CWE-190 - Integer overflow
Exploit availability: Yes
DescriptionThe vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to integer overflow in BCrypt class with the maximum work factor (31) for BCryptPasswordEncoder. The encoder does not perform any salt rounds, which weakens encryption capabilities of the software.
Install update from vendor's website.
