Language:

Synopsis

The remote SUSE host is missing one or more security updates.

Description

The remote SUSE Linux SUSE15 host has a package installed that is affected by multiple vulnerabilities as referenced in the openSUSE-SU-2022:10187-1 advisory.

- A privilege escalation to root exists in Eternal Terminal prior to version 6.2.0. This is due to the combination of a race condition, buffer overflow, and logic bug all in PipeSocketHandler::listen().
(CVE-2022-24949)

- A race condition exists in Eternal Terminal prior to version 6.2.0 that allows an authenticated attacker to hijack other users' SSH authorization socket, enabling the attacker to login to other systems as the targeted users. The bug is in UserTerminalRouter::getInfoForId(). (CVE-2022-24950)

- A race condition exists in Eternal Terminal prior to version 6.2.0 which allows a local attacker to hijack Eternal Terminal's IPC socket, enabling access to Eternal Terminal clients which attempt to connect in the future. (CVE-2022-24951)

- Several denial of service vulnerabilities exist in Eternal Terminal prior to version 6.2.0, including a DoS triggered remotely by an invalid sequence number and a local bug triggered by invalid input sent directly to the IPC socket. (CVE-2022-24952)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected EternalTerminal package.
