OpenSSH: OpenSSH: Information disclosure due to unintended cryptographic algorithm usage

A flaw was found in OpenSSH. This vulnerability allows the system to use unintended Elliptic Curve Digital Signature Algorithm ECDSA algorithms. This occurs because the configuration for accepted public key algorithms is misinterpreted, leading to the use of weaker cryptographic methods than...

OpenSSH: OpenSSH: Arbitrary command execution via shell metacharacters in username

A flaw was found in OpenSSH. This vulnerability allows a remote attacker to achieve arbitrary command execution by injecting shell metacharacters into a username provided on the command line. Exploitation requires an untrusted username and a non-default configuration of the '%' character in...

OpenSSH: OpenSSH: Privilege escalation via scp legacy protocol when not preserving file mode

A flaw was found in OpenSSH. When the scp command is used by a root user to download a file with the legacy protocol option -O and without preserving original file permissions -p, the downloaded file can be installed with elevated privileges setuid or setgid. This unexpected behavior could allow ...

OpenSSH: OpenSSH: Security bypass via mishandling of authorized_keys principals option

A flaw was found in OpenSSH. This vulnerability arises from the incorrect handling of the authorizedkeys principals option in uncommon scenarios. Specifically, when a principals list is used with a Certificate Authority that includes comma characters, OpenSSH may misinterpret the input. This coul...

OpenSSH: OpenSSH: Low integrity impact from unconfirmed proxy-mode multiplexing sessions

A flaw was found in OpenSSH. This vulnerability allows for a low integrity impact due to the omission of connection multiplexing confirmation for proxy-mode multiplexing sessions. A local user, under specific and complex conditions requiring user interaction, could potentially establish a...
