CVE-2020-12063

The CVE-2020-12063 issue affects Postfix 2.10.1-7 and enables spoofed outbound mail via a homoglyph attack (30F) that resembles a configured sender when /etc/postfix/sender_login is used. Multiple connected sources (SUSE, Red Hat, UB Ubuntu/BPO feeds) confirm that an attacker could send mail fr...

Arbitrary Code Execution

postfix is vulnerable to arbitrary code execution. A heap-based buffer over-read flaw was found in the way Postfix performed SASL handlers management for SMTP sessions, when Cyrus SASL authentication was enabled. A remote attacker could use this flaw to cause the Postfix smtpd server to crash via...

Information Disclosure

postfix is vulnerable to information disclosure. It was discovered that Postfix did not properly check the permissions of users' mailbox files. A local attacker able to create files in the mail spool directory could use this flaw to create mailbox files for other local users, and be able to read...

Command Injection

postfix is vulnerable to command injection. It was discovered that Postfix did not flush the received SMTP commands buffer after switching to TLS encryption for an SMTP session. A man-in-the-middle attacker could use this flaw to inject SMTP commands into a victim's session during the plain text...

Privilege Escalation

postfix is vulnerable to privilege escalation. A flaw was found in the way Postfix dereferences symbolic links. If a local user has write access to a mail spool directory with no root mailbox, it may be possible for them to append arbitrary data to files that root has write permission to...

Incorrect Query Responses

postfixmtastsresolver provides incorrect query responses. It can happen due to a lack of improper parsing of query responses from daemon under some conditions, resulting in effective STS policy downgrade...
