DESCRIPTION:
Jeroen van Wolffelaar has reported a vulnerability in Open OBEX,
which can be exploited by malicious people to manipulate certain data
on a user's system.

The vulnerability is caused due to "ircp_io.c" failing to check for
existing files with the same name before replacing them with files
that are sent by another user. This can potentially be exploited to
replace files in the user's current directory.

Successful exploitation requires that the user has accepted a file
transfer from another user.

The vulnerability has been reported in version 1.2. Other versions
may also be affected.

SOLUTION:
Do not accept file transfers from untrusted users.
