Security Bulletin
This security bulletin contains information about 3 vulnerabilities.
1) Improper Authentication
EUVDB-ID: #VU55334
Risk: Medium
CVSSv4.0: 1.7 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Green]
CVE-ID: CVE-2021-3652
CWE-ID:
CWE-287 - Improper Authentication
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to bypass authentication process.
The vulnerability exists due to an error in the way the asterisk character is processed by the LDAP server when importing password hashes from /etc/shadow for disabled accounts. As a result of the flaw, if an LDAP admin imports such an account from a NIS or /etc/shadow database into Directory Server, any password will be valid for that account.
Update the affected package 389-ds to the latest version.

2) Use-after-free
EUVDB-ID: #VU60867
Risk: Medium
CVSSv4.0: 4.6 [CVSS:4.0/AV:A/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green]
CVE-ID: CVE-2021-4091
CWE-ID:
CWE-416 - Use After Free
Exploit availability: No
DescriptionThe vulnerability allows a remote user to perform a denial of service (DoS) attack.
The vulnerability exists due to a use-after-free error when processing virtual attributes context in persistent searches. A remote user can send specially crafted search requests to the directory server, trigger a use-after-free error and crash the server.
Update the affected package 389-ds to the latest version.

3) Incorrect authorization
EUVDB-ID: #VU64440
Risk: Medium
CVSSv4.0: 4.6 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green]
CVE-ID: CVE-2022-1949
CWE-ID:
CWE-863 - Incorrect Authorization
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform a denial of service attack.
The vulnerability exists due to incorrect authorization in the 389-ds-base package where some LDAP queries can cause performance issues. A remote attacker can send a non-optimal search that causes serious performance issues within the directory server.
MitigationUpdate the affected package 389-ds to the latest version.
