Package: openssh-server Version: 1:9.2p1-2+deb12u3 Severity: normal X-Debbugs-Cc: sa-dev@odd.systems
Dear Maintainer, When an SSH client connects with the `-v` option for verbose logging, the OpenSSH server discloses the full path to the `authorized_keys` file and specific key options in use. This information is exposed in the debug logs during the handshake process: debug1: Remote: /...path.../authorized_keys:1: key options: command debug1: Remote: /...path.../authorized_keys:1: key options: agent-forwarding port-forwarding pty user-rc x11-forwarding This behavior can undermine the security of a restricted shell setup by revealing sensitive configuration details. Steps to Reproduce: 1. Connect to the SSH server using an SSH client with the `-v` option. 2. Observe the debug output revealing the full path and key options. Expected Behavior: The server should not disclose sensitive information such as file paths or specific key options in verbose logs, preserving configuration confidentiality. Thank you for addressing this issue. -- System Information: Debian Release: 12.7 APT prefers stable-updates APT policy: (500, 'stable-updates'), (500, 'stable-security'), (500, 'stable') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 6.1.0-25-amd64 (SMP w/8 CPU threads; PREEMPT) Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8), LANGUAGE not set Shell: /bin/sh linked to /usr/bin/dash Init: systemd (via /run/systemd/system) Versions of packages openssh-server depends on: ii adduser 3.134 ii debconf [debconf-2.0] 1.5.82 ii init-system-helpers 1.65.2 ii libaudit1 1:3.0.9-1 ii libc6 2.36-9+deb12u8 ii libcom-err2 1.47.0-2 ii libcrypt1 1:4.4.33-2 ii libgssapi-krb5-2 1.20.1-2+deb12u2 ii libkrb5-3 1.20.1-2+deb12u2 ii libpam-modules 1.5.2-6+deb12u1 ii libpam-runtime 1.5.2-6+deb12u1 ii libpam0g 1.5.2-6+deb12u1 ii libselinux1 3.4-1+b6 ii libssl3 3.0.14-1~deb12u2 ii libsystemd0 252.30-1~deb12u2 ii libwrap0 7.6.q-32 ii lsb-base 11.6 ii openssh-client 1:9.2p1-2+deb12u3 ii openssh-sftp-server 1:9.2p1-2+deb12u3 ii procps 2:4.0.2-3 ii runit-helper 2.15.2 ii sysvinit-utils [lsb-base] 3.06-4 ii ucf 3.0043+nmu1 ii zlib1g 1:1.2.13.dfsg-1 Versions of packages openssh-server recommends: ii libpam-systemd [logind] 252.30-1~deb12u2 ii xauth 1:1.1.2-1
