Summary
openssh vulnerabilities
Details

It was discovered that OpenSSH incorrectly handled supplemental groups when running helper programs for AuthorizedKeysCommand and AuthorizedPrincipalsCommand as a different user. An attacker could possibly use this issue to escalate privileges. This issue only affected Ubuntu 20.04 LTS. (CVE-2021-41617)

It was discovered that OpenSSH incorrectly added destination constraints when PKCS#11 token keys were added to ssh-agent, contrary to expectations. This issue only affected Ubuntu 22.04 LTS, and Ubuntu 23.04. (CVE-2023-51384)

It was discovered that OpenSSH incorrectly handled user names or host names with shell metacharacters. An attacker could possibly use this issue to perform OS command injection. (CVE-2023-51385)
