6.8
Média
| Vetor | AV:N/AC:L/Au:S/C:N/I:N/A:C |
Name of the Vulnerable Software and Affected Versions
samba versions 4.0.0 through 4.9.14
samba versions 4.10.x through 4.10.9
Description
A flaw in the samba software allows an attacker to crash the AD DC LDAP server via dirsync, resulting in denial of service. The issue is related to a null pointer dereference in the LDAP dirsync component. Privilege escalation is not possible with this issue. The vulnerability can be exploited by a remote attacker to cause a denial of service.
Recommendations
For samba versions 4.0.0 through 4.9.14, update to version 4.9.15 or later.
For samba versions 4.10.x through 4.10.9, update to version 4.10.10 or later.
As a temporary workaround, consider restricting access to the dirsync component to minimize the risk of exploitation.
