Introduction to Integer Overflows and Underflows Video - 00:02:00 This video provides an introduction to the integer overflows and underflows course. Meet the author Howard Poston Howard Poston is a copywriter, author, and course developer with experience in cybersecurity and blockchain security,...
Most integer overflow conditions simply lead to erroneous program behavior but do not cause any vulnerabilities. However, in some cases, integer overflows may have severe consequences: If an integer overflow happens when you calculate the length of a buffer, you may end up with a buffer overflow...
Automatically identifying this kind of vulnerability is critical for software security. Despite many works have been done to mitigate integer overflow, existing tools either report large number of false positives or introduce unacceptable time consumption. To address this problem, in this article we ...
What is an overflow in integer arithmetic? Overflow occurs when an arithmetic operation on integers produces a result that is too large to be represented using the available number of bits. This can lead to incorrect computation results or unexpected behavior in a computer program. To avoid overfl...
Integer overflow [CWE-190] Impact: Denial of service Remotely Exploitable: No Locally Exploitable: Yes CVE Name: CVE-2013-5058 3. *Vulnerability Description* Windows kernel is prone to a security vulnerability when executing the (GDI support) function 'RFONTOBJ::bTextExtent' located in 'win32k...

overflow is, in fact, an announced feature, and can be used deliberately to obtain interesting results (for instance, to perform a modulo operation inside a random-number generator). But most of the time, when programmers use integers, they would prefer not to be threatened by overflows. If...
2. this allows for efficient arithmetic operations like addition or subtraction, as well as bitwise operations like and or xor. the exact format and size of integers may vary depending on the computer architecture and the programming language being used. what is an overflow in integer arithmetic?
