SingCERT's Security Bulletin summarises the list of vulnerabilities collated from the National Institute of Standards and Technology (NIST)'s National Vulnerability Database (NVD) in the past week. Show The vulnerabilities are tabled based on severity, in accordance to their CVSSv3 base scores: For those vulnerabilities without assigned CVSS scores, please visit NVD for the updated CVSS vulnerability entries.
What is the most common buffer overflow attack?Stack overflow attack - This is the most common type of buffer overflow attack and involves overflowing a buffer on the call stack*. Heap overflow attack - This type of attack targets data in the open memory pool known as the heap*.
What is buffer overflow malware?A buffer overflow is a type of software vulnerability that exists when an area of memory within a software application reaches its address boundary and writes into an adjacent memory region. In software exploit code, two common areas that are targeted for overflows are the stack and the heap.
What are some common buffer overflow attacks?Some types of buffer overflow attacks include the following.. Stack-based buffer overflow or stack buffer overrun attack. The stack holds data in a last-in, first-out structure. ... . Heap-based buffer overflow attack. ... . Integer overflow attack. ... . Format strings attack. ... . Unicode overflow attacks.. What is the most effective solution to buffer overflow attacks?Buffer Overflow Solutions
The most reliable way to avoid or prevent buffer overflows is to use automatic protection at the language level. Another fix is bounds-checking enforced at run-time, which prevents buffer overrun by automatically checking that data written to a buffer is within acceptable boundaries.
