| CVE-2010-2024 | 1 Exim | 1 Exim | 2025-04-11 | N/A |
| transports/appendfile.c in Exim before 4.72, when MBX locking is enabled, allows local users to change permissions of arbitrary files or create arbitrary files, and cause a denial of service or possibly gain privileges, via a symlink attack on a lockfile in /tmp/. | ||||
| CVE-2010-2023 | 1 Exim | 1 Exim | 2025-04-11 | N/A |
| transports/appendfile.c in Exim before 4.72, when a world-writable sticky-bit mail directory is used, does not verify the st_nlink field of mailbox files, which allows local users to cause a denial of service or possibly gain privileges by creating a hard link to another user's file. | ||||
| CVE-2025-26794 | 1 Exim | 1 Exim | 2025-02-22 | 7.5 High |
| Exim 4.98 before 4.98.1, when SQLite hints and ETRN serialization are used, allows remote SQL injection. | ||||
| CVE-2023-51766 | 3 Debian, Exim, Fedoraproject | 4 Debian Linux, Exim, Extra Packages For Enterprise Linux and 1 more | 2024-11-21 | 5.3 Medium |
| Exim before 4.97.1 allows SMTP smuggling in certain PIPELINING/CHUNKING configurations. Remote attackers can use a published exploitation technique to inject e-mail messages with a spoofed MAIL FROM address, allowing bypass of an SPF protection mechanism. This occurs because Exim supports <LF>.<CR><LF> but some other popular e-mail servers do not. | ||||
| CVE-2023-42119 | 1 Exim | 1 Exim | 2024-11-21 | 3.1 Low |
| Exim dnsdb Out-Of-Bounds Read Information Disclosure Vulnerability. This vulnerability allows network-adjacent attackers to disclose sensitive information on affected installations of Exim. Authentication is not required to exploit this vulnerability. The specific flaw exists within the smtp service, which listens on TCP port 25 by default. The issue results from the lack of proper validation of user-supplied data, which can result in a read past the end of an allocated buffer. An attacker can leverage this in conjunction with other vulnerabilities to execute arbitrary code in the context of the service account. . Was ZDI-CAN-17643. | ||||
| CVE-2023-42117 | 1 Exim | 1 Exim | 2024-11-21 | 8.1 High |
| Exim Improper Neutralization of Special Elements Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Exim. Authentication is not required to exploit this vulnerability. The specific flaw exists within the smtp service, which listens on TCP port 25 by default. The issue results from the lack of proper validation of user-supplied data, which can result in a memory corruption condition. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-17554. | ||||
| CVE-2023-42116 | 1 Exim | 1 Exim | 2024-11-21 | 8.1 High |
| Exim SMTP Challenge Stack-based Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Exim. Authentication is not required to exploit this vulnerability. The specific flaw exists within the handling of NTLM challenge requests. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of the service account. . Was ZDI-CAN-17515. | ||||
| CVE-2023-42115 | 1 Exim | 1 Exim | 2024-11-21 | 9.8 Critical |
| Exim AUTH Out-Of-Bounds Write Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Exim. Authentication is not required to exploit this vulnerability. The specific flaw exists within the smtp service, which listens on TCP port 25 by default. The issue results from the lack of proper validation of user-supplied data, which can result in a write past the end of a buffer. An attacker can leverage this vulnerability to execute code in the context of the service account. . Was ZDI-CAN-17434. | ||||
| CVE-2023-42114 | 1 Exim | 1 Exim | 2024-11-21 | 3.7 Low |
| Exim NTLM Challenge Out-Of-Bounds Read Information Disclosure Vulnerability. This vulnerability allows remote attackers to disclose sensitive information on affected installations of Exim. Authentication is not required to exploit this vulnerability. The specific flaw exists within the handling of NTLM challenge requests. The issue results from the lack of proper validation of user-supplied data, which can result in a read past the end of an allocated data structure. An attacker can leverage this vulnerability to disclose information in the context of the service account. . Was ZDI-CAN-17433. | ||||
| CVE-2022-37452 | 2 Debian, Exim | 2 Debian Linux, Exim | 2024-11-21 | 9.8 Critical |
| Exim before 4.95 has a heap-based buffer overflow for the alias list in host_name_lookup in host.c when sender_host_name is set. | ||||
| CVE-2022-37451 | 2 Exim, Fedoraproject | 2 Exim, Fedora | 2024-11-21 | 7.5 High |
| Exim before 4.96 has an invalid free in pam_converse in auths/call_pam.c because store_free is not used after store_malloc. | ||||
| CVE-2021-38371 | 1 Exim | 1 Exim | 2024-11-21 | 7.5 High |
| The STARTTLS feature in Exim through 4.94.2 allows response injection (buffering) during MTA SMTP sending. | ||||
| CVE-2021-27216 | 1 Exim | 1 Exim | 2024-11-21 | 6.3 Medium |
| Exim 4 before 4.94.2 has Execution with Unnecessary Privileges. By leveraging a delete_pid_file race condition, a local user can delete arbitrary files as root. This involves the -oP and -oPX options. | ||||
| CVE-2020-8015 | 2 Exim, Opensuse | 2 Exim, Opensuse | 2024-11-21 | 8.4 High |
| A UNIX Symbolic Link (Symlink) Following vulnerability in the packaging of exim in openSUSE Factory allows local attackers to escalate from user mail to root. This issue affects: openSUSE Factory exim versions prior to 4.93.0.4-3.1. | ||||
| CVE-2020-28026 | 1 Exim | 1 Exim | 2024-11-21 | 9.8 Critical |
| Exim 4 before 4.94.2 has Improper Neutralization of Line Delimiters, relevant in non-default configurations that enable Delivery Status Notification (DSN). Certain uses of ORCPT= can place a newline into a spool header file, and indirectly allow unauthenticated remote attackers to execute arbitrary commands as root. | ||||
| CVE-2020-28025 | 1 Exim | 1 Exim | 2024-11-21 | 7.5 High |
| Exim 4 before 4.94.2 allows Out-of-bounds Read because pdkim_finish_bodyhash does not validate the relationship between sig->bodyhash.len and b->bh.len; thus, a crafted DKIM-Signature header might lead to a leak of sensitive information from process memory. | ||||
| CVE-2020-28024 | 1 Exim | 1 Exim | 2024-11-21 | 9.8 Critical |
| Exim 4 before 4.94.2 allows Buffer Underwrite that may result in unauthenticated remote attackers executing arbitrary commands, because smtp_ungetc was only intended to push back characters, but can actually push back non-character error codes such as EOF. | ||||
| CVE-2020-28023 | 1 Exim | 1 Exim | 2024-11-21 | 7.5 High |
| Exim 4 before 4.94.2 allows Out-of-bounds Read. smtp_setup_msg may disclose sensitive information from process memory to an unauthenticated SMTP client. | ||||
| CVE-2020-28022 | 1 Exim | 1 Exim | 2024-11-21 | 9.8 Critical |
| Exim 4 before 4.94.2 has Improper Restriction of Write Operations within the Bounds of a Memory Buffer. This occurs when processing name=value pairs within MAIL FROM and RCPT TO commands. | ||||
| CVE-2020-28021 | 1 Exim | 1 Exim | 2024-11-21 | 8.8 High |
| Exim 4 before 4.94.2 has Improper Neutralization of Line Delimiters. An authenticated remote SMTP client can insert newline characters into a spool file (which indirectly leads to remote code execution as root) via AUTH= in a MAIL FROM command. | ||||
