Does Java have buffer overflows? If yes can you give me scenarios?
606
Buffer overflow occurs when data is input or written beyond the allocated bounds of an object, causing a program crash or creating a vulnerability that attackers might exploit.
Buffer overflows can affect all types of software. They typically result from malformed inputs or failure to allocate enough space for the buffer. If the transaction overwrites executable code, it can cause the program to behave unpredictably and generate incorrect results, memory access errors, or crashes.
Description. Buffer overflow is probably the best known form of software security vulnerability. Most software developers know what a buffer overflow vulnerability is, but buffer overflow attacks against both legacy and newly-developed applications are still quite common.
The following is the source code of a C program that has a buffer overflow vulnerability: char greeting[5]; memcpy(greeting, "Hello, world!\ n", 15);
Since Java Strings are based on char arrays and Java automatically checks array bounds, buffer overflows are only possible in unusual scenarios:

Managed languages such as Java and C# do not have these problems, but the specific virtual machines (JVM/CLR/etc) which actually run the code may.
