1.修復(fù)的CVE ·CVE-2015-5252 描述：Samba是Samba團(tuán)隊(duì)開發(fā)的一套可使UNIX系列的操作系統(tǒng)與微軟Windows操作系統(tǒng)的SMB/CIFS網(wǎng)絡(luò)協(xié)議做連結(jié)的自由軟件，它支持共享打印機(jī)、互相傳輸資料文件等。smbd是其中的一個(gè)用于向客戶端（如Windows 95、98、ME，Windows NT和Windows 2000等）提供文件共享和打印服務(wù)的服務(wù)器進(jìn)程。Samba的smbd守護(hù)進(jìn)程中的vfs.c文件中存在安全漏洞。當(dāng)程序共享的路徑名與文件系統(tǒng)中的其他路徑名共同使用路徑的前綴時(shí)，遠(yuǎn)程攻擊者可借助指向非共享路徑的符號(hào)鏈接，利用該漏洞繞過既定的文件訪問權(quán)限。以下版本受到影響：Samba 4.1.22之前3.x版本和4.x版本，4.2.7之前4.2.x版本，4.3.3之前4.3.x版本。 ·CVE-2015-5296 描述：Samba是Samba團(tuán)隊(duì)開發(fā)的一套可使UNIX系列的操作系統(tǒng)與微軟Windows操作系統(tǒng)的SMB/CIFS網(wǎng)絡(luò)協(xié)議做連結(jié)的自由軟件。該軟件支持共享打印機(jī)、互相傳輸資料文件等。Samba中存在安全漏洞，該漏洞源于程序支持加密但未簽名的連接。攻擊者可通過修改client-server數(shù)據(jù)流利用該漏洞實(shí)施中間人攻擊和encrypted-to-unencrypted降級(jí)攻擊。以下版本受到影響：Samba

4.1.22之前3.x版本和4.x版本，4.2.7之前4.2.x版本，4.3.3之前4.3.x版本。 ·CVE-2015-5330 描述：Samba是Samba團(tuán)隊(duì)開發(fā)的一套可使UNIX系列的操作系統(tǒng)與微軟Windows操作系統(tǒng)的SMB/CIFS網(wǎng)絡(luò)協(xié)議做連結(jié)的自由軟件。該軟件支持共享打印機(jī)、互相傳輸資料文件等。AD LDAP server是其中的一個(gè)輕量級(jí)目錄訪問協(xié)議服務(wù)器。ldb是一個(gè)類似于LDAP的嵌入式數(shù)據(jù)庫。Samba的AD LDAP服務(wù)器中使用的ldb中存在安全漏洞，該漏洞源于程序沒有正確處理字符串長度。遠(yuǎn)程攻擊者可通過發(fā)送特制的數(shù)據(jù)包并讀取錯(cuò)誤消息或數(shù)據(jù)庫值，利用該漏洞獲取守護(hù)進(jìn)程堆內(nèi)存中的敏感信息。以下產(chǎn)品及版本受到影響：Samba 4.1.22之前4.x版本，4.2.7之前4.2.x版本，4.3.3之前4.3.x版本，ldb 1.1.24之前版本。 ·CVE-2015-7560
