公告标识 CVE-2015-5370 | |
标题 | CVE-2015-5370 |
描述 | Multiple flaws were found in Samba's DCE/RPC protocol implementation. A remote, authenticated attacker could use these flaws to cause a denial of service against the Samba server (high CPU load or a crash) or, possibly, execute arbitrary code with the permissions of the user running Samba (root). This flaw could also be used to downgrade a secure DCE/RPC connection by a man-in-the-middle attacker taking control of an Active Directory (AD) object and compromising the security of a Samba Active Directory Domain Controller (DC). |

Bugzilla | 1309987: CVE-2015-5370 samba: crash in dcesrv_auth_bind_ack due to missing error check |
详细信息 | https://access.redhat.com/security/cve/cve-2015-5370 |
公告标识 CVE-2016-2118 | |
标题 | CVE-2016-2118 |
描述 | A protocol flaw, publicly referred to as Badlock, was found in the Security Account Manager Remote Protocol (MS-SAMR) and the Local Security Authority (Domain Policy) Remote Protocol (MS-LSAD). Any authenticated DCE/RPC connection that a client initiates against a server could be used by a man-in-the-middle attacker to impersonate the authenticated user against the SAMR or LSA service on the server. As a result, the attacker would be able to get read/write access to the Security Account Manager database, and use this to reveal all passwords or any other potentially sensitive information in that database. |
