| CVE-2023-42115 | 1 Exim | 1 Exim | 2024-09-20 | 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-2023-42116 | 1 Exim | 1 Exim | 2024-09-18 | 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-2023-42114 | 1 Exim | 1 Exim | 2024-09-18 | 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-2010-4344 | 5 Canonical, Debian, Exim and 2 more | 6 Ubuntu Linux, Debian Linux, Exim and 3 more | 2024-08-07 | 9.8 Critical |
| Heap-based buffer overflow in the string_vformat function in string.c in Exim before 4.70 allows remote attackers to execute arbitrary code via an SMTP session that includes two MAIL commands in conjunction with a large message containing crafted headers, leading to improper rejection logging. | ||||
| CVE-2010-2024 | 1 Exim | 1 Exim | 2024-08-07 | 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 | 2024-08-07 | 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-2011-1764 | 1 Exim | 1 Exim | 2024-08-06 | N/A |
| Format string vulnerability in the dkim_exim_verify_finish function in src/dkim.c in Exim before 4.76 might allow remote attackers to execute arbitrary code or cause a denial of service (daemon crash) via format string specifiers in data used in DKIM logging, as demonstrated by an identity field containing a % (percent) character. | ||||
| CVE-2011-1407 | 1 Exim | 1 Exim | 2024-08-06 | N/A |
| The DKIM implementation in Exim 4.7x before 4.76 permits matching for DKIM identities to apply to lookup items, instead of only strings, which allows remote attackers to execute arbitrary code or access a filesystem via a crafted identity. | ||||
| CVE-2011-0017 | 1 Exim | 1 Exim | 2024-08-06 | N/A |
| The open_log function in log.c in Exim 4.72 and earlier does not check the return value from (1) setuid or (2) setgid system calls, which allows local users to append log data to arbitrary files via a symlink attack. | ||||
| CVE-2012-5671 | 1 Exim | 1 Exim | 2024-08-06 | N/A |
| Heap-based buffer overflow in the dkim_exim_query_dns_txt function in dkim.c in Exim 4.70 through 4.80, when DKIM support is enabled and acl_smtp_connect and acl_smtp_rcpt are not set to "warn control = dkim_disable_verify," allows remote attackers to execute arbitrary code via an email from a malicious DNS server. | ||||
| CVE-2014-2972 | 1 Exim | 1 Exim | 2024-08-06 | N/A |
| expand.c in Exim before 4.83 expands mathematical comparisons twice, which allows local users to gain privileges and execute arbitrary commands via a crafted lookup value. | ||||
