"iDefense reports :

Remote exploitation of a stack based buffer overflow vulnerability in
RARLabs Unrar may allow an attacker to execute arbitrary code with the
privileges of the user opening the archive.

Unrar is prone to a stack based buffer overflow when processing
specially crafted password protected archives.

If users are using the vulnerable command line based unrar, they still
need to interact with the program in order to trigger the
vulnerability. They must respond to the prompt asking for the
password, after which the vulnerability will be triggered. They do not
need to enter a correct password, but they must at least push the
enter key."
