GLSA-201911-01 : OpenSSH: Integer overflow

The remote host is affected by the vulnerability described in GLSA-201911-01 OpenSSH: Integer overflow OpenSSH, when built with xmss USE flag enabled, has a pre-authentication integer overflow if a client or server is configured to use a crafted XMSS key. NOTE: This USE flag is disabled by defaul...

OpenSSH: Integer overflow

Background OpenSSH is a complete SSH protocol implementation that includes SFTP client and server support. Description OpenSSH, when built with “xmss” USE flag enabled, has a pre-authentication integer overflow if a client or server is configured to use a crafted XMSS key. NOTE: This USE flag is...

Access Restrictions Bypass

openssh is vulnerable to access restrictions bypass. Due to improper parsing of filenames such as . or empty filenames, the SCP client allows remote SSH servers to bypass access restrictions and perform unauthorized configuration of directory permissions on the client-side...

Arbitrary File Overwrite

openssh is vulnerable to Arbitrary File Overwrite. Improper validation of object names allows a malicious server to overwrite files on the client-side via scp client...

openssh: Improper validation of object names allows malicious server to overwrite files via scp client

An issue was discovered in OpenSSH 7.9. Due to the scp implementation being derived from 1983 rcp, the server chooses which files/directories are sent to the client. However, the scp client only performs cursory validation of the object name returned only directory traversal attacks are prevented...

openssh: Missing character encoding in progress display allows for spoofing of scp client output

An issue was discovered in OpenSSH 7.9. Due to missing character encoding in the progress display, a malicious server or Man-in-The-Middle attacker can employ crafted object names to manipulate the client output, e.g., by using ANSI control codes to hide additional files being transferred. This...

openssh: scp client improper directory name validation

In OpenSSH 7.9, scp.c in the scp client allows remote SSH servers to bypass intended access restrictions via the filename of . or an empty filename. The impact is modifying the permissions of the target directory on the client side...

CVE-2019-16905

A Denial of service flaw was found in the way OpenSSH parsed certain specially crafted XMSS eXtended Merkle Signature Scheme private keys. Any OpenSSH functionality which parses private keys is vulnerable, for example: 1. If ‘sshd’ daemon is configured to use an XMSS host key that is malformed, i...
