EulerOS 2.0 SP12 : libssh (EulerOS-SA-2026-1093)

low Nessus Plugin ID 284732

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 libssh's handling of key exchange (KEX) processes when a client repeatedly sends incorrect KEX guesses. The library fails to free memory during these rekey operations, which can gradually exhaust system memory. This issue can lead to crashes on the client side, particularly when using libgcrypt, which impacts application stability and availability.(CVE-2025-8277)

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
