CVE-2016-0778

HIGH 8.1EPSS 20.9%

Does this matter?

EPSS puts the probability of exploitation in the next 30 days at 20.9%, higher than 97% of all known CVEs. Patch or mitigate before the next change window.

Description

The (1) roaming_read and (2) roaming_write functions in roaming_common.c in the client in OpenSSH 5.x, 6.x, and 7.x before 7.1p2, when certain proxy and forward options are enabled, do not properly maintain connection file descriptors, which allows remote servers to cause a denial of service (heap-based buffer overflow) or possibly have unspecified other impact by requesting many forwardings.
