libssh2: libssh2: Arbitrary code execution via heap buffer overflow during SSH negotiation

A flaw was found in libssh2. A malicious SSH server can exploit a pre-authentication heap buffer overflow vulnerability by sending a specially crafted packet during the Encrypt-then-MAC ETM cipher negotiation. This allows the server to corrupt heap memory, potentially leading to arbitrary code...

libssh2: libssh2: Arbitrary code execution via double-free in SFTP session

A flaw was found in libssh2. A malicious SSH Secure Shell server can exploit a double-free vulnerability in the sftpopen function. This flaw allows the server to corrupt the heap memory of an authenticated client when it opens an SFTP SSH File Transfer Protocol session. This heap corruption can...

CVE-2026-14837 SSH Enablement Signature Verification Bypass

Multiple Lenze products are affected by an improper signature verification vulnerability in the SSH enablement mechanism. A low-privileged local attacker can bypass verification of the SSH enable file signature and enable SSH access on the device. Successful exploitation may result in unauthorize...
