| Package | Affected versions | Patched versions |
|---|---|---|
| samba | ≥ 4.0.0, < 4.1.22 | 4.1.22 |
The LDAP server in the AD domain controller in Samba 4.x before 4.1.22 does not check return values to ensure successful ASN.1 memory allocation, which allows remote attackers to cause a denial of service (memory consumption and daemon crash) via crafted packets.
