medium Nessus Plugin ID 276462

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 :

There's a vulnerability in the libssh package where when a libssh consumer passes in an unexpectedly large input buffer to ssh_get_fingerprint_hash() function. In such cases the bin_to_base64() function can experience an integer overflow leading to a memory under allocation, when that happens it's possible that the program perform out of bounds write leading to a heap corruption.
This issue affects only 32-bits builds of libssh.(CVE-2025-4877)

A vulnerability, which was classified as problematic, was found in libssh up to 0.11.1.This is going to have an impact on confidentiality, integrity, and availability.Upgrading to version 0.11.2 eliminates this vulnerability.(CVE-2025-5372)

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
