| CVE-2008-2936 | 1 Postfix | 1 Postfix | 2023-02-12 | 6.2 MEDIUM | N/A |
| Postfix before 2.3.15, 2.4 before 2.4.8, 2.5 before 2.5.4, and 2.6 before 2.6-20080814, when the operating system supports hard links to symlinks, allows local users to append e-mail messages to a file to which a root-owned symlink points, by creating a hard link to this symlink and then sending a message. NOTE: this can be leveraged to gain privileges if there is a symlink to an init script. | |||||
| CVE-2020-12063 | 1 Postfix | 1 Postfix | 2022-05-03 | 5.0 MEDIUM | 5.3 MEDIUM |
| ** DISPUTED ** A certain Postfix 2.10.1-7 package could allow an attacker to send an email from an arbitrary-looking sender via a homoglyph attack, as demonstrated by the similarity of \xce\xbf to the 'o' character. This is potentially relevant when the /etc/postfix/sender_login feature is used, because a spoofed outbound message that uses a configured sender address is blocked with a "Sender address rejected: not logged in" error message, but a spoofed outbound message that uses a homoglyph of a configured sender address is not blocked. NOTE: some third parties argue that any missed blocking of spoofed outbound messages - except for exact matches to a sender address in the /etc/postfix/sender_login file - is outside the design goals of Postfix and thus cannot be considered a Postfix vulnerability. | |||||
| CVE-2011-0411 | 1 Postfix | 1 Postfix | 2021-08-10 | 6.8 MEDIUM | N/A |
| The STARTTLS implementation in Postfix 2.4.x before 2.4.16, 2.5.x before 2.5.12, 2.6.x before 2.6.9, and 2.7.x before 2.7.3 does not properly restrict I/O buffering, which allows man-in-the-middle attackers to insert commands into encrypted SMTP sessions by sending a cleartext command that is processed after TLS is in place, related to a "plaintext command injection" attack. | |||||
| CVE-2017-10140 | 1 Postfix | 1 Postfix | 2020-07-15 | 4.6 MEDIUM | 7.8 HIGH |
| Postfix before 2.11.10, 3.0.x before 3.0.10, 3.1.x before 3.1.6, and 3.2.x before 3.2.2 might allow local users to gain privileges by leveraging undocumented functionality in Berkeley DB 2.x and later, related to reading settings from DB_CONFIG in the current directory. | |||||
| CVE-2008-3889 | 2 Linux, Postfix | 2 Linux Kernel, Postfix | 2018-10-11 | 2.1 LOW | N/A |
| Postfix 2.4 before 2.4.9, 2.5 before 2.5.5, and 2.6 before 2.6-20080902, when used with the Linux 2.6 kernel, leaks epoll file descriptors during execution of "non-Postfix" commands, which allows local users to cause a denial of service (application slowdown or exit) via a crafted command, as demonstrated by a command in a .forward file. | |||||
| CVE-2008-2937 | 1 Postfix | 1 Postfix | 2018-10-11 | 1.9 LOW | N/A |
| Postfix 2.5 before 2.5.4 and 2.6 before 2.6-20080814 delivers to a mailbox file even when this file is not owned by the recipient, which allows local users to read e-mail messages by creating a mailbox file corresponding to another user's account name. | |||||
| CVE-2011-1720 | 1 Postfix | 1 Postfix | 2018-10-09 | 6.8 MEDIUM | N/A |
| The SMTP server in Postfix before 2.5.13, 2.6.x before 2.6.10, 2.7.x before 2.7.4, and 2.8.x before 2.8.3, when certain Cyrus SASL authentication methods are enabled, does not create a new server handle after client authentication fails, which allows remote attackers to cause a denial of service (heap memory corruption and daemon crash) or possibly execute arbitrary code via an invalid AUTH command with one method followed by an AUTH command with a different method. | |||||
| CVE-2012-0811 | 1 Postfix | 1 Postfix | 2014-10-02 | 6.5 MEDIUM | N/A |
| Multiple SQL injection vulnerabilities in Postfix Admin (aka postfixadmin) before 2.3.5 allow remote authenticated users to execute arbitrary SQL commands via (1) the pw parameter to the pacrypt function, when mysql_encrypt is configured, or (2) unspecified vectors that are used in backup files generated by backup.php. | |||||
| CVE-2009-2939 | 3 Debian, Postfix, Ubuntu | 3 Debian Linux, Postfix, Ubuntu Linux | 2011-08-23 | 6.9 MEDIUM | N/A |
| The postfix.postinst script in the Debian GNU/Linux and Ubuntu postfix 2.5.5 package grants the postfix user write access to /var/spool/postfix/pid, which might allow local users to conduct symlink attacks that overwrite arbitrary files. | |||||
| CVE-2008-4977 | 1 Postfix | 1 Postfix | 2008-11-06 | 6.9 MEDIUM | N/A |
| ** DISPUTED ** postfix_groups.pl in Postfix 2.5.2 allows local users to overwrite arbitrary files via a symlink attack on the (1) /tmp/postfix_groups.stdout, (2) /tmp/postfix_groups.stderr, and (3) /tmp/postfix_groups.message temporary files. NOTE: the vendor disputes this vulnerability, stating "This is not a real issue ... users would have to edit a script under /usr/lib to enable it." | |||||
