CVE-2017-5668
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.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (2.98%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
