CVE-2010-4345 1 Exim 1 Exim 2023-02-12 6.9 MEDIUM N/A
Exim 4.72 and earlier allows local users to gain privileges by leveraging the ability of the exim user account to specify an alternate configuration file with a directive that contains arbitrary commands, as demonstrated by the spool_directory directive.
CVE-2010-4344 1 Exim 1 Exim 2023-02-12 9.3 HIGH N/A
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-2022-3620 2 Exim, Fedoraproject 2 Exim, Fedora 2023-01-19 N/A 9.8 CRITICAL
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 2022-11-16 N/A 7.5 HIGH
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-2019-10149 3 Canonical, Debian, Exim 3 Ubuntu Linux, Debian Linux, Exim 2022-11-07 10.0 HIGH 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-2022-37452 2 Debian, Exim 2 Debian Linux, Exim 2022-10-28 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-2020-28017 1 Exim 1 Exim 2022-10-04 7.5 HIGH 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-2022-37451 2 Exim, Fedoraproject 2 Exim, Fedora 2022-09-29 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-2020-28026 1 Exim 1 Exim 2022-07-12 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-2020-28012 1 Exim 1 Exim 2022-07-12 7.2 HIGH 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-2020-28014 1 Exim 1 Exim 2022-07-12 5.6 MEDIUM 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-2019-16928 4 Canonical, Debian, Exim and 1 more 4 Ubuntu Linux, Debian Linux, Exim and 1 more 2022-03-31 7.5 HIGH 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-2020-28010 1 Exim 1 Exim 2021-12-03 7.2 HIGH 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-2020-28020 1 Exim 1 Exim 2021-09-03 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-2021-38371 1 Exim 1 Exim 2021-08-20 5.0 MEDIUM 7.5 HIGH
The STARTTLS feature in Exim through 4.94.2 allows response injection (buffering) during MTA SMTP sending.
CVE-2018-6789 3 Canonical, Debian, Exim 3 Ubuntu Linux, Debian Linux, Exim 2021-06-03 7.5 HIGH 9.8 CRITICAL
An issue was discovered in the base64d function in the SMTP listener in Exim before 4.90.1. By sending a handcrafted message, a buffer overflow may happen. This can be used to execute code remotely.
CVE-2020-28018 1 Exim 1 Exim 2021-05-26 7.5 HIGH 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-2021-27216 1 Exim 1 Exim 2021-05-13 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-2020-28007 1 Exim 1 Exim 2021-05-10 7.2 HIGH 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-2020-28008 1 Exim 1 Exim 2021-05-10 7.2 HIGH 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.
