Vulnerability in OpenSSH (CVE-2012-0814)
Summary
Vulnerability in OpenSSH (CVE-2012-0814). Risk of unauthorized operations or information disclosure.
Original description
The description as published by the source.
The auth_parse_options function in auth-options.c in sshd in OpenSSH before 5.7 provides debug messages containing authorized_keys command options, which allows remote authenticated users to obtain potentially sensitive information by reading these messages, as demonstrated by the shared user account required by Gitolite. NOTE: this can cross privilege boundaries because a user account may intentionally have no shell or filesystem access, and therefore may have no supported way to read an authorized_keys file in its own home directory.
