CVE-2001-0572
HighSummary
SSH protocols 1 and 2, as implemented in OpenSSH and other packages, have various weaknesses that can allow a remote attacker to obtain information via sniffing. Attackers may learn about password lengths, the type of authentication used, and the lengths of shell commands.
Risk Assessment
These weaknesses can facilitate brute force attacks and provide attackers with system information, increasing the risk of unauthorized access.
Recommendation
It is recommended to update to the latest version of OpenSSH and implement additional security measures such as using strong passwords and SSH keys.

SEPPmail Secure Email Gateway before 15.1.1 trusts a file path supplied in externally provided Large File Transfer attachment metadata. An unauthenticated remote sender can cause the mail-processing worker to disclose, move, or delete an accessible regular file when LFT is enabled and the message reaches an affected secure-mail processing path. The validated workers ran as root.

SEPPmail Secure Email Gateway before 15.1.1 can evaluate attacker-influenced replacement text as Perl code in sender or recipient replacement rules. An unauthenticated remote sender can execute operating-system commands in the mail-processing worker context when an active rule uses message-derived replacement data and its search condition matches. The validated worker context was root.

Original NVD description (English source)
The SSH protocols 1 and 2 (aka SSH-2) as implemented in OpenSSH and other packages have various weaknesses which can allow a remote attacker to obtain the following information via sniffing: (1) password lengths or ranges of lengths, which simplifies brute force password guessing, (2) whether RSA or DSA authentication is being used, (3) the number of authorized_keys in RSA authentication, or (4) the lengths of shell commands.
