# find-fake-fast
## Description
Find candidate fake fast or tcache chunks overlapping the specified address.
## Usage:
```bash
usage: find-fake-fast [-h] [--align] [--glibc-fastbin-bug]
[--partial-overwrite]
target_address [max_candidate_size]
```
## Positional Arguments
|Positional Argument|Help|
| :--- | :--- |
|`target_address`|Address of the word-sized value to overlap.|
|`max_candidate_size`|Maximum size of fake chunks to find.|
## Optional Arguments
|Short|Long|Default|Help|
| :--- | :--- | :--- | :--- |
|`-h`|`--help`||show this help message and exit|
|`-a`|`--align`||Whether the fake chunk must be aligned to MALLOC_ALIGNMENT. This is required for tcache chunks and for all chunks when Safe Linking is enabled|
|`-b`|`--glibc-fastbin-bug`||Does the GLIBC fastbin size field bug affect the candidate size field width?|
|`-p`|`--partial-overwrite`||Consider partial overwrite candidates, default behavior only shows word-size overwrites.|
