| CVE-2023-51766 | 3 Debian, Exim, Fedoraproject | 4 Debian Linux, Exim, Extra Packages For Enterprise Linux and 1 more | 2024-11-21 | 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-2022-3620 | 2 Exim, Fedoraproject | 2 Exim, Fedora | 2024-11-21 | N/A | 5.6 MEDIUM |
| A vulnerability was found in Exim and classified as problematic. This issue affects the function dmarc_dns_lookup of the file dmarc.c of the component DMARC Handler. The manipulation leads to use after free. The attack may be initiated remotely. The name of the patch is 12fb3842f81bcbd4a4519d5728f2d7e0e3ca1445. It is recommended to apply a patch to fix this issue. The associated identifier of this vulnerability is VDB-211919. | |||||
| CVE-2022-3559 | 2 Exim, Fedoraproject | 2 Exim, Fedora | 2024-11-21 | N/A | 4.6 MEDIUM |
| A vulnerability was found in Exim and classified as problematic. This issue affects some unknown processing of the component Regex Handler. The manipulation leads to use after free. The name of the patch is 4e9ed49f8f12eb331b29bd5b6dc3693c520fddc2. It is recommended to apply a patch to fix this issue. The identifier VDB-211073 was assigned to this vulnerability. | |||||
| CVE-2022-37452 | 2 Debian, Exim | 2 Debian Linux, Exim | 2024-11-21 | N/A | 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 | N/A | 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 | 5.0 MEDIUM | 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 | 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 | 7.2 HIGH | 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 | 9.3 HIGH | 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 | 5.0 MEDIUM | 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 | 7.5 HIGH | 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 | 5.0 MEDIUM | 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 | 7.5 HIGH | 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 | 9.0 HIGH | 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. | |||||
| CVE-2020-28020 | 1 Exim | 1 Exim | 2024-11-21 | 7.5 HIGH | 9.8 CRITICAL |
| Exim 4 before 4.92 allows Integer Overflow to Buffer Overflow, in which an unauthenticated remote attacker can execute arbitrary code by leveraging the mishandling of continuation lines during header-length restriction. | |||||
| CVE-2020-28019 | 1 Exim | 1 Exim | 2024-11-21 | 5.0 MEDIUM | 7.5 HIGH |
| Exim 4 before 4.94.2 has Improper Initialization that can lead to recursion-based stack consumption or other consequences. This occurs because use of certain getc functions is mishandled when a client uses BDAT instead of DATA. | |||||
