|---|---|---|---|---|
| CVE-2019-16928 | 4 Canonical, Debian, Exim and 1 more | 4 Ubuntu Linux, Debian Linux, Exim and 1 more | 2024-08-05 | 9.8 Critical |
| Exim 4.92 through 4.92.2 allows remote code execution, a different vulnerability than CVE-2019-15846. There is a heap-based buffer overflow in string_vformat in string.c involving a long EHLO command. | ||||
| CVE-2019-15846 | 2 Debian, Exim | 2 Debian Linux, Exim | 2024-08-05 | N/A |
| Exim before 4.92.2 allows remote attackers to execute arbitrary code as root via a trailing backslash. | ||||
| CVE-2019-13917 | 2 Debian, Exim | 2 Debian Linux, Exim | 2024-08-05 | N/A |
| Exim 4.85 through 4.92 (fixed in 4.92.1) allows remote code execution as root in some unusual configurations that use the ${sort } expansion for items that can be controlled by an attacker (e.g., $local_part or $domain). | ||||
| CVE-2019-10149 | 3 Canonical, Debian, Exim | 3 Ubuntu Linux, Debian Linux, Exim | 2024-08-04 | 9.8 Critical |
| A flaw was found in Exim versions 4.87 to 4.91 (inclusive). Improper validation of recipient address in deliver_message() function in /src/deliver.c may lead to remote command execution. | ||||
| CVE-2020-28010 | 1 Exim | 1 Exim | 2024-08-04 | 7.8 High |
| Exim 4 before 4.94.2 allows Out-of-bounds Write because the main function, while setuid root, copies the current working directory pathname into a buffer that is too small (on some common platforms). | ||||
| CVE-2020-28023 | 1 Exim | 1 Exim | 2024-08-04 | 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-2020-28021 | 1 Exim | 1 Exim | 2024-08-04 | 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-2020-28019 | 1 Exim | 1 Exim | 2024-08-04 | 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. | ||||
| CVE-2020-28008 | 1 Exim | 1 Exim | 2024-08-04 | 7.8 High |
| Exim 4 before 4.94.2 allows Execution with Unnecessary Privileges. Because Exim operates as root in the spool directory (owned by a non-root user), an attacker can write to a /var/spool/exim4/input spool header file, in which a crafted recipient address can indirectly lead to command execution. | ||||
| CVE-2020-28009 | 1 Exim | 1 Exim | 2024-08-04 | 7.8 High |
| Exim 4 before 4.94.2 allows Integer Overflow to Buffer Overflow because get_stdinput allows unbounded reads that are accompanied by unbounded increases in a certain size variable. NOTE: exploitation may be impractical because of the execution time needed to overflow (multiple days). | ||||
| CVE-2020-28016 | 1 Exim | 1 Exim | 2024-08-04 | 7.8 High |
| Exim 4 before 4.94.2 allows an off-by-two Out-of-bounds Write because "-F ''" is mishandled by parse_fix_phrase. | ||||
| CVE-2020-28007 | 1 Exim | 1 Exim | 2024-08-04 | 7.8 High |
| Exim 4 before 4.94.2 allows Execution with Unnecessary Privileges. Because Exim operates as root in the log directory (owned by a non-root user), a symlink or hard link attack allows overwriting critical root-owned files anywhere on the filesystem. | ||||
| CVE-2020-28018 | 1 Exim | 1 Exim | 2024-08-04 | 9.8 Critical |
| Exim 4 before 4.94.2 allows Use After Free in smtp_reset in certain situations that may be common for builds with OpenSSL. | ||||
| CVE-2020-28011 | 1 Exim | 1 Exim | 2024-08-04 | 7.8 High |
| Exim 4 before 4.94.2 allows Heap-based Buffer Overflow in queue_run via two sender options: -R and -S. This may cause privilege escalation from exim to root. | ||||
| CVE-2020-28017 | 1 Exim | 1 Exim | 2024-08-04 | 9.8 Critical |
| Exim 4 before 4.94.2 allows Integer Overflow to Buffer Overflow in receive_add_recipient via an e-mail message with fifty million recipients. NOTE: remote exploitation may be difficult because of resource consumption. | ||||
| CVE-2020-28022 | 1 Exim | 1 Exim | 2024-08-04 | 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-2020-28024 | 1 Exim | 1 Exim | 2024-08-04 | 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-2020-28014 | 1 Exim | 1 Exim | 2024-08-04 | 6.1 Medium |
| Exim 4 before 4.94.2 allows Execution with Unnecessary Privileges. The -oP option is available to the exim user, and allows a denial of service because root-owned files can be overwritten. | ||||
| CVE-2020-28012 | 1 Exim | 1 Exim | 2024-08-04 | 7.8 High |
| Exim 4 before 4.94.2 allows Exposure of File Descriptor to Unintended Control Sphere because rda_interpret uses a privileged pipe that lacks a close-on-exec flag. | ||||
| CVE-2020-28025 | 1 Exim | 1 Exim | 2024-08-04 | 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. | ||||
