CVE-2001-1459
HighSummary
OpenSSH 2.9 and earlier does not initiate a Pluggable Authentication Module (PAM) session if commands are executed with no pty, allowing local users to bypass resource limits (rlimits) set in pam.d.
Risk Assessment
Local users may exploit this vulnerability to exceed resource limits, potentially leading to system overload or unauthorized access to resources.
Recommendation
It is recommended to upgrade OpenSSH to a newer version that improves PAM session handling and to implement additional security measures to restrict local user access.

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.
