# RARLAB UnRAR before 6.12 on Linux and UNIX allows directory traversal to write to files during an extract (aka…

RARLAB UnRAR on Linux and UNIX has a directory traversal flaw that lets a crafted RAR archive write files outside the extraction directory during unpacking. An attacker who gets a victim to extract a malicious archive can overwrite files on the system.

_Summary, check and fix written by a model from the sources; labelled as such._

## Affected

- vendor:rarlab unrar affected < 6.12 fixed 6.12
- vendor:debian linux affected = 10.0 fixed ?
- vendor:RARLAB UnRAR affected ? fixed ?

## Fix
