Security Bulletin
This security bulletin contains information about 4 vulnerabilities.
1) Resource exhaustion
EUVDB-ID: #VU69392
Risk: Medium
CVSSv3.1: 6.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2022-45061
CWE-ID:
CWE-400 - Resource exhaustion
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to usage of an unnecessary quadratic algorithm in one path when processing some inputs to the IDNA (RFC 3490) decoder. A remote attacker can pass a specially crafted name to he decoder, trigger resource excessive CPU consumption and perform a denial of service (DoS) attack.
MitigationInstall update from vendor's website.
Vulnerable software versionsOracle Database Server: 21c
