CVE-2020-28020 1 Exim 1 Exim 2024-11-21 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 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-2020-28018 1 Exim 1 Exim 2024-11-21 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-2020-28017 1 Exim 1 Exim 2024-11-21 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-2020-28016 1 Exim 1 Exim 2024-11-21 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-2020-28015 1 Exim 1 Exim 2024-11-21 7.8 High
Exim 4 before 4.94.2 has Improper Neutralization of Line Delimiters. Local users can alter the behavior of root processes because a recipient address can have a newline character.
CVE-2020-28014 1 Exim 1 Exim 2024-11-21 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-2020-28013 1 Exim 1 Exim 2024-11-21 7.8 High
Exim 4 before 4.94.2 allows Heap-based Buffer Overflow because it mishandles "-F '.('" on the command line, and thus may allow privilege escalation from any user to root. This occurs because of the interpretation of negative sizes in strncpy.
CVE-2020-28012 1 Exim 1 Exim 2024-11-21 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-2020-28011 1 Exim 1 Exim 2024-11-21 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-2020-28010 1 Exim 1 Exim 2024-11-21 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-2020-28009 1 Exim 1 Exim 2024-11-21 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 2024-11-21 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-2020-28007 1 Exim 1 Exim 2024-11-21 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-2020-12783 4 Canonical, Debian, Exim and 1 more 4 Ubuntu Linux, Debian Linux, Exim and 1 more 2024-11-21 7.5 High
Exim through 4.93 has an out-of-bounds read in the SPA authenticator that could result in SPA/NTLM authentication bypass in auths/spa.c and auths/auth-spa.c.
CVE-2019-16928 4 Canonical, Debian, Exim and 1 more 4 Ubuntu Linux, Debian Linux, Exim and 1 more 2024-11-21 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 2024-11-21 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 2024-11-21 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 2024-11-21 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-2018-6789 3 Canonical, Debian, Exim 3 Ubuntu Linux, Debian Linux, Exim 2024-11-21 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.
