bitlbee-libpurple before 3.5.1 allows remote attackers to cause a denial of service (NULL pointer dereference and crash) and possibly execute arbitrary code via a file transfer request for a contact that is not in the contact list. NOTE: this vulnerability exists because of an incomplete fix for CVE-2016-10189.

Weakness

A NULL pointer dereference occurs when the application dereferences a pointer that it expects to be valid, but is NULL, typically causing a crash or exit.
