+ Remote
Type
+ Denial of service
Description
+ Receiving a file transfer request from a contact not in the contact list results in a null pointer dereference, leading to remote DoS by malicious remote clients. Additionally, due to an incomplete fix of the issue above in BitlBee 3.5, the bitlbee-libpurple variant is still affected in 3.5.

Notes
+ This results in denial of service (remote crash of the BitlBee
+ instance). Remote code execution does not seem to be possible (fixed
+ offset)
+
+ For BitlBee servers configured in ForkDaemon mode (default) or inetd
+ mode, the crash is limited to one user connection, who may just
+ reconnect.
