Affected Systems: MySQL AB MySQL Describe: MySQL is a very extensive open source relational database system with a running version of various platforms. On MySQL, a user with access rights but no create permission can create a new database that differs only from the name of the database being accessed. Successful exploitation of this vulnerability requires the file system running MySQL to support case-sensitive file names. In addition, because the parameters of the Suid routine are computed

Similar to Oracle! There are two types of privileges: database-level privileges (for all objects in the database) and Object-level privileges (associated with specific objects ). Database-level privileges that users can possess: Createtab: You

. Not all abilities have a right to match, so it is not possible to use power exactly to match the group's built-in capabilities. And because The predefined allocation of specific group capabilities and the inability to copy all capabilities into power make it difficult to distinguish between tasks and only the concept of least privilege is enforced. Then there is a lack of a security structure at the dom

Preface: Everyone should have forgotten three years ago before the Serv-U5.004 version of all versions of the "Serv-U ftpmtm Command Buffer Overflow" and "Serv-u ftp Server LIST Command ultra-long-l Parameter Remote Buffer overflow Vulnerability, this vulnerability has left many server administrators restless, and many large websites and even telecom-grade servers down... with the launch of the new Serv-U version, this leakage does not exist. Although the overflow does not exist, hackers will ne

Vamei Source: Http://www.cnblogs.com/vamei Welcome reprint, Please also keep this statement. Thank you!As a Linux user, we don't need to be particularly concerned with the following mechanisms. However, when we write a Linux application, we should pay attention to the implementation of the following switches in the program (if necessary), so that our program conforms to the "least privilege" principle, do not leave the system a potential

Absrtact: A design and implementation scheme of privilege management system based on RBAC model is proposed. This paper introduces the multilayer architecture design of Java EE architecture, expounds the design idea of role-based access control RBAC model, and discusses the core object-oriented design model of the privilege management system, as well as the key technologies such as permission access,

Microsoft's. NET component has a severe overflow vulnerability. Any operating system installed with the. NET component will be affected by this vulnerability. That is to say, Windows XP, Windows 7, Windows 2003, and Winodws 2008, which are the most widely used website servers, cannot be spared. So what does this vulnerability mean for hackers? What kind of storm will the network security community face? Read this article. ★Edit prompt: Hazards of loc

A personal summary of the privilege level in the IA32 segmentation mechanism: In IA32 's segmented mechanism, it is divided into 4 privilege levels (RING0~RING3): Level0 High (inner layer)L e v E l 1L e v E l 2L e v E l 3 Low (outer) The difference between the privilege levels is the restriction of the instruction (mainly the limitation of the system instruction
