WinRAR Delete File Buffer Overflow Vulnerability

[Mobo]

Vafa Khoshaein has discovered a vulnerability in WinRAR, which can be exploited by malicious people to compromise a user's system.

The vulnerability is caused due to a boundary error in the handling of filenames when deleting files in archives. This can be exploited to cause a buffer overflow by tricking a user into deleting a file in an opened, malicious archive.

Successful exploitation may allow execution of arbitrary code.

The vulnerability has been confirmed on versions 3.40 and 3.41. Other versions may also be affected.

Solution:
Do not delete files in untrusted archives.
