Vulnerability Title
N/A
Source: NVD (National Vulnerability Database)
Vulnerability Description
A flaw was found in samba versions 4.0.0 to 4.5.2. The Samba routine ndr_pull_dnsp_name contains an integer wrap problem, leading to an attacker-controlled memory overwrite. ndr_pull_dnsp_name parses data from the Samba Active Directory ldb database. Any user who can write to the dnsRecord attribute over LDAP can trigger this memory corruption. By default, all authenticated LDAP users can write to the dnsRecord attribute on new DNS objects. This makes the defect a remote privilege escalation.

Source: CNNVD (China National Vulnerability Database)
Vulnerability Description
Samba是Samba团队的一套可使UNIX系列的操作系统与微软Windows操作系统的SMB/CIFS网络协议做连结的自由软件。该软件支持共享打印机、互相传输资料文件等。 Samba 4.0.0版本至4.5.2版本存在基于堆的缓冲区溢出漏洞，该漏洞源于程序没有正确的对用户提交的数据执行边界检测，导致程序复制数据的大小超出了分配的内存缓冲区空间。攻击者可借助恶意的dnsRecord属性利用该漏洞在受影响应用程序上下文中执行任意代码，可能导致拒绝服务。
