CVE-2017-17432 is a vulnerability of currently unknown severity. OpenAFS 1.x before 1.6.22 does not properly validate Rx ack packets, which allows remote attackers to cause a denial of service (system crash or application crash) via crafted fields, as demonstrated by an integer underflow and assertion failure for a small MTU value.. EPSS estimates a 3.05% chance of exploitation in the next 30 days.
