漏洞描述
中文描述:
OpenLDAP是美国OpenLDAP基金会的一个轻型目录访问协议（LDAP）的自由和开源实现，它已被包含在Linux发行版中。 OpenLDAP在处理Kerberos Bind请求时存在缓冲区溢出漏洞，远程攻击者可能利用此漏洞在服务器上执行任意指令。 OpenLDAP代码的servers/slapd/kerberos.c文件中的krbv4_ldap_auth函数存在缓冲区溢出漏洞，该函数处理指定了LDAP_AUTH_KRBV41认证方式的LDAP bind请求，cred变量包含有指向客户端所发送Kerberos认证数据的指针。由于在将其拷贝到栈上固定大小缓冲区之前没有检查数据长度，因此攻击者可以通过发送大于1250字节的bind请求触发溢出，导致执行任意指令。漏洞代码如下： krbv4_ldap_auth( Backend *be, struct berval *cred, AUTH_DAT *ad ) { KTEXT_ST k; KTEXT ktxt = &k; char instance[INST_SZ]; int err; Debug( LDAP_DEBUG_TRACE, "=> kerberosv4_ldap_auth\n", 0, 0, 0 ); AC_MEMCPY( ktxt->dat, cred->bv_val, cred->bv_len ); ktxt->length = cred->bv_len; 请注意必须以"--enable-kbind"选项编译了OpenLDAP才可能存在这个漏洞。
英文描述:
Buffer overflow in the krbv4_ldap_auth function in servers/slapd/kerberos.c in OpenLDAP 2.4.3 and earlier, when OpenLDAP is compiled with the --enable-kbind (Kerberos KBIND) option, allows remote attackers to execute arbitrary code via an LDAP bind request using the LDAP_AUTH_KRBV41 authentication method and long credential data.
