The command to execute with NBFIFO input
Specifies the target program or script that will be tested for buffer overflows.
DESCRIPTION
The `nbfifteen` command is a Linux utility designed to detect buffer overflows in programs by leveraging Named Buffer FIFOs (NBFIFO). It creates a special FIFO file, writes carefully crafted data patterns to it (often exploiting the 'fifteen' value in some way, implying a specific size or alignment vulnerability), and then directs the target program to read from this FIFO as input. By observing the program's behavior (e.g., crashes, unexpected output, or security alerts), `nbfifteen` can help identify potential buffer overflow vulnerabilities that are triggered when the program attempts to write beyond the allocated buffer space during input handling. The command aims to simplify the process of fuzzing and vulnerability discovery by providing a controlled and repeatable method to test input-related security weaknesses.
CAVEATS
The effectiveness of `nbfifteen` depends on the target program's input handling mechanisms and the specific vulnerabilities present. It may require experimentation with different data patterns and input lengths to trigger vulnerabilities. Also, `nbfifteen` itself could be vulnerable to security issues depending on its implementation.
USAGE EXAMPLES
Simple example
`nbfifteen ./myprogram` - Runs 'myprogram' with specially crafted input from NBFIFO.
Verbose mode
`nbfifteen -v ./myprogram` - Runs 'myprogram' with verbose output.
