CVE-2015-7540

Name of the Vulnerable Software and Affected Versions Samba versions prior to 4.1.22

Description The issue is related to the LDAP server in the AD domain controller in Samba, where it fails to check return values for successful ASN.1 memory allocation. This allows remote attackers to cause a denial of service, resulting in memory consumption and daemon crash, via crafted packets. The vulnerability is associated with an error in the resource management mechanism of the system.

Recommendations For versions prior to 4.1.22, update to version 4.1.22 or later to resolve the issue. As a temporary workaround, consider restricting access to the LDAP server to minimize the risk of exploitation.
