CVE-2015-5352 is a vulnerability of currently unknown severity. The x11_open_helper function in channels.c in ssh in OpenSSH before 6.9, when ForwardX11Trusted mode is not used, lacks a check of the refusal deadline for X connections, which makes it easier for remote attackers to bypass intended access restrictions via a connection outside of the permitted time window.. EPSS estimates a 5.45% chance of exploitation in the next 30 days.
