Title: OpenSSH vulnerabilities
Summary: Several security issues were fixed in OpenSSH.
It was discovered that OpenSSH sftp did not properly constrain the location
of downloaded files when connecting to an attacker-controlled server. An
attacker could possibly use this issue to write files to unintended
locations on the file system. (CVE-2026-59995)
It was discovered that OpenSSH scp could place files in the parent
directory of the intended destination when copying between two remote
hosts. An attacker could possibly use this issue to write files to
unintended locations. (CVE-2026-59996)
It was discovered that OpenSSH internal-sftp only recognized the first nine
command-line arguments, This could result in certain security-sensitive
arguments being ignored, contrary to expectations. (CV

CVE-2026-60000 [LOW] CWE-307 openssh: OpenSSH: Denial of Service via excessive GSSAPI authentication attempts
openssh: OpenSSH: Denial of Service via excessive GSSAPI authentication attempts
A flaw was found in OpenSSH's Secure Shell Daemon (sshd). This vulnerability allows a remote attacker to cause a denial of service by initiating an excessive number of authentication attempts. The issue arises from the mishandling of the MaxAuthTries setting specifically when using GSSAPIAuthentication, leading to resource exhaustion.
