high Tenable Cloud Security Plugin ID 460349

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - A flaw was found in libssh. During SFTP server directory listing, the longname field is constructed with
 unsafe concatenation into a fixed-size stack buffer. When a client causes the server to list attacker-
 controlled filenames, sufficiently long names can overflow that stack buffer and may lead to crashes or
 possible code execution on the server. (CVE-2026-15370)

Solution

Update the libssh library and its related packages to version 0.12.0-3+e2 or later.
