The detailed semantics of "the" ternary operator as well as its syntax differs significantly from language to language. A top level distinction from one language to another is whether the expressions permit side effects (as in most procedural languages) and whether the language provides short-circuit evaluation semantics, whereby only the selected expression is evaluated (most standard ...
A "return-to-libc" attack is a computer security attack usually starting with a buffer overflow in which a subroutine return address on a call stack is replaced by an address of a subroutine that is already present in the process executable memory, bypassing the no-execute bit feature (if present) and ridding the attacker of the need to inject their own code.
[5] [6] Code injection could, for example: Introduce a useful new column that did not appear in the original design of a search results page. Offer a new way to filter, order, or group data by using a field not exposed in the default functions of the original design. Add functionality like connecting to online resources in an offline program.
Major DBMSs, including SQLite, [5] MySQL, [6] Oracle, [7] IBM Db2, [8] Microsoft SQL Server [9] and PostgreSQL [10] support prepared statements. Prepared statements are normally executed through a non-SQL binary protocol for efficiency and protection from SQL injection, but with some DBMSs such as MySQL prepared statements are also available using a SQL syntax for debugging purposes.
A remote exploit works over a network and exploits the security vulnerability without any prior access to the vulnerable system. A local exploit requires prior access or physical access to the vulnerable system, and usually increases the privileges of the person running the exploit past those granted by the system administrator. Exploits ...
This led to the first posting in September 1999 on the Bugtraq mailing list regarding this class of vulnerabilities, including a basic exploit. [6] It was still several months, however, before the security community became aware of the full dangers of format string vulnerabilities as exploits for other software using this method began to surface.
Augmented assignment (or compound assignment) is the name given to certain assignment operators in certain programming languages (especially those derived from C).An augmented assignment is generally used to replace a statement where an operator takes a variable as one of its arguments and then assigns the result back to the same variable.
Spring Security is a Java/Java EE framework that provides authentication, authorization and other security features for enterprise applications. The project was started in late 2003 as 'Acegi Security' (pronounced Ah-see-gee / ɑː s iː dʒ iː /, whose letters are the first, third, fifth, seventh, and ninth characters from the English alphabet, in order to prevent name conflicts [2]) by Ben ...
