CVE-2018-6789 | 3 Canonical, Debian, Exim | 3 Ubuntu Linux, Debian Linux, Exim | 2024-07-25 | 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-2019-16928 | 4 Canonical, Debian, Exim and 1 more | 4 Ubuntu Linux, Debian Linux, Exim and 1 more | 2024-07-24 | 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-2010-4344 | 4 Canonical, Debian, Exim and 1 more | 4 Ubuntu Linux, Debian Linux, Exim and 1 more | 2024-07-16 | 9.3 HIGH | 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-2010-4345 | 4 Canonical, Debian, Exim and 1 more | 4 Ubuntu Linux, Debian Linux, Exim and 1 more | 2024-07-16 | 6.9 MEDIUM | 7.8 HIGH |
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-2023-51766 | 3 Debian, Exim, Fedoraproject | 4 Debian Linux, Exim, Extra Packages For Enterprise Linux and 1 more | 2024-02-28 | 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 | 2024-02-28 | 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-2022-37452 | 2 Debian, Exim | 2 Debian Linux, Exim | 2024-02-28 | 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-2022-3559 | 2 Exim, Fedoraproject | 2 Exim, Fedora | 2024-02-28 | 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-2022-37451 | 2 Exim, Fedoraproject | 2 Exim, Fedora | 2024-02-28 | 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-2020-28018 | 1 Exim | 1 Exim | 2024-02-28 | 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-2020-28023 | 1 Exim | 1 Exim | 2024-02-28 | 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-2020-28007 | 1 Exim | 1 Exim | 2024-02-28 | 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-2020-28020 | 1 Exim | 1 Exim | 2024-02-28 | 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-2020-28012 | 1 Exim | 1 Exim | 2024-02-28 | 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-2021-38371 | 1 Exim | 1 Exim | 2024-02-28 | 5.0 MEDIUM | 7.5 HIGH |
The STARTTLS feature in Exim through 4.94.2 allows response injection (buffering) during MTA SMTP sending. | |||||
CVE-2020-28019 | 1 Exim | 1 Exim | 2024-02-28 | 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. | |||||
CVE-2020-28025 | 1 Exim | 1 Exim | 2024-02-28 | 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-2020-28009 | 1 Exim | 1 Exim | 2024-02-28 | 7.2 HIGH | 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-2020-28008 | 1 Exim | 1 Exim | 2024-02-28 | 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. | |||||
CVE-2020-28022 | 1 Exim | 1 Exim | 2024-02-28 | 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. |
