| CVE-2025-67896 | 1 Exim | 1 Exim | 2026-10-14 | N/A | 7.0 HIGH |
| Exim before 4.99.1, with certain non-default rate-limit configurations, allows a remote heap-based buffer overflow because database records are cast directly to internal structures without validation. | |||||
| CVE-2026-94054 | 1 Exim | 1 Exim | 2026-09-24 | N/A | 7.0 HIGH |
| Exim before 4.100.1, when Proxy-Protocol is used with an attacker-controlled proxy, has an out-of-bounds write. | |||||
| CVE-2026-94055 | 1 Exim | 1 Exim | 2026-09-24 | N/A | 3.7 LOW |
| Exim before 4.100.1, when certain non-default TLS settings are used with GnuTLS, has a use-after-free. | |||||
| CVE-2026-94056 | 1 Exim | 1 Exim | 2026-09-24 | N/A | 7.5 HIGH |
| Exim before 4.100.1, when Proxy-Protocol is used with an attacker-controlled proxy, allows attackers to read certain uninitialized data from stack memory. | |||||
| CVE-2026-94057 | 1 Exim | 1 Exim | 2026-09-24 | N/A | 4.0 MEDIUM |
| Exim before 4.100.1 allows SMTP smuggling in which the received message does not match any sent message, and instead depends on crafted data sent after a rejection during DATA processing. | |||||
| CVE-2026-66141 | 1 Exim | 1 Exim | 2026-08-17 | N/A | 7.4 HIGH |
| Exim before 4.99.5 allows .forward privilege escalation because force_command for a pipe transport is mishandled. | |||||
| CVE-2026-66140 | 1 Exim | 1 Exim | 2026-08-17 | N/A | 8.4 HIGH |
| Exim before 4.99.5 allows directory traversal to access files outside of the spool area, and consequently gain privileges, because arguments related to queue-name are mishandled. | |||||
| CVE-2026-48840 | 1 Exim | 1 Exim | 2026-07-22 | N/A | 5.3 MEDIUM |
| Exim 4.88 before 4.99.4, in some proxy configurations, mishandles certain short payloads, leading to disclosure of uninitialized stack memory values to a client. | |||||
| CVE-2026-45185 | 1 Exim | 1 Exim | 2026-06-17 | N/A | 9.8 CRITICAL |
| Exim before 4.99.3, in certain GnuTLS configurations, has a remotely reachable use-after-free in the BDAT body parsing path. It is triggered when a client sends a TLS close_notify mid-body during a CHUNKING transfer, followed by a final cleartext byte on the same TCP connection. This can lead to heap corruption. An unauthenticated network attacker exploiting this vulnerability could execute arbitrary code. | |||||
| CVE-2026-40687 | 1 Exim | 1 Exim | 2026-06-17 | N/A | 4.8 MEDIUM |
| In Exim before 4.99.2, when the SPA authentication driver is used with an adversarial SPA resource, there can be an out-of-bounds write that crashes the connection instance, or erroneous data processing that divulges data from uninitialized heap memory. | |||||
| CVE-2026-40686 | 1 Exim | 1 Exim | 2026-06-17 | N/A | 3.7 LOW |
| In Exim before 4.99.2, when utf8 operators are enabled, there is an out-of-bounds read if large UTF-8 trailing characters are present (malformed UTF-8 header data). Information might be divulged within an error message produced during handling of an unrelated e-mail message. | |||||
| CVE-2026-40685 | 1 Exim | 1 Exim | 2026-06-17 | N/A | 6.5 MEDIUM |
| In Exim before 4.99.2, when JSON lookup is enabled, an out-of-bounds heap write can occur when a JSON operator encounters malformed JSON in an untrusted header, because of an incorrect implementation of \ skipping. | |||||
| CVE-2026-40684 | 1 Exim | 1 Exim | 2026-06-17 | N/A | 5.9 MEDIUM |
| In Exim before 4.99.2, on systems using musl libc (not glibc), an attacker can crash the connection instance when malformed DNS data is present in PTR records. This is caused by a dn_expand oddity in octal printing. | |||||
| CVE-2025-30232 | 1 Exim | 1 Exim | 2026-06-17 | N/A | 8.1 HIGH |
| A use-after-free in Exim 4.96 through 4.98.1 could allow users (with command-line access) to escalate privileges. | |||||
| CVE-2025-26794 | 1 Exim | 1 Exim | 2026-06-17 | N/A | 7.5 HIGH |
| Exim 4.98 before 4.98.1, when SQLite hints and ETRN serialization are used, allows remote SQL injection. (Resolving SQL injection requires an update to 4.99.1 in certain non-default rate-limit configurations.) | |||||
| CVE-2024-39929 | 1 Exim | 1 Exim | 2026-06-17 | N/A | 5.4 MEDIUM |
| Exim through 4.97.1 misparses a multiline RFC 2231 header filename, and thus remote attackers can bypass a $mime_filename extension-blocking protection mechanism, and potentially deliver executable attachments to the mailboxes of end users. | |||||
| CVE-2023-51766 | 3 Debian, Exim, Fedoraproject | 4 Debian Linux, Exim, Extra Packages For Enterprise Linux and 1 more | 2026-06-17 | N/A | 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 | 2026-06-17 | N/A | 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-2023-42118 | 2 Exim, Libspf2 Project | 2 Exim, Libspf2 | 2026-06-17 | N/A | 8.8 HIGH |
| Exim libspf2 Integer Underflow Remote Code Execution Vulnerability. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of Exim libspf2. Authentication is not required to exploit this vulnerability. The specific flaw exists within the parsing of SPF macros. When parsing SPF macros, the process does not properly validate user-supplied data, which can result in an integer underflow before writing to memory. An attacker can leverage this vulnerability to execute code in the context of the service account. . Was ZDI-CAN-17578. | |||||
| CVE-2023-42117 | 1 Exim | 1 Exim | 2026-06-17 | N/A | 9.8 CRITICAL |
| 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. | |||||
