RARLabs Unrar Password Prompt Buffer Overflow Vulnerability
Un <http://www.rarlabs.com/> rar is a command line archive extractor for
Windows and Linux.
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
* Unrar version 3.60 for Linux
* Unrar version 3.61 for Windows.
* (Previous versions may also be affected.)
* Unrar version 3.70 for Linux
Exploitation of the vulnerability could allow an attacker to execute
arbitrary code with the privileges of the user opening the file.
Exploitation would require that an attacker hosts a maliciously crafted

techniques to trick the e-mail recipient into opening the document.

not vulnerable. If users are using the vulnerable command line based

RARLabs has addressed this vulnerability with the version 3.70 beta
release of WinRAR.
