EulerOS 2.0 SP12 : libssh (EulerOS-SA-2025-2047)

high Nessus Plugin ID 264416

Synopsis

The remote EulerOS host is missing a security update.

Description

According to the versions of the libssh package installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

 A flaw was found in the libssh library. An out-of-bounds read can be triggered in the sftp_handle function due to an incorrect comparison check that permits the function to access memory beyond the valid handle list and to return an invalid pointer, which is used in further processing. This vulnerability allows an authenticated remote attacker to potentially read unintended memory regions, exposing sensitive information or affect service behavior.(CVE-2025-5318)

Tenable has extracted the preceding description block directly from the EulerOS libssh security advisory.

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

Solution
