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-2019-15846 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-2017-16944 2 Debian, Exim 2 Debian Linux, Exim 2024-11-21 N/A
The receive_msg function in receive.c in the SMTP daemon in Exim 4.88 and 4.89 allows remote attackers to cause a denial of service (infinite loop and stack exhaustion) via vectors involving BDAT commands and an improper check for a '.' character signifying the end of the content, related to the bdat_getc function.
CVE-2017-16943 2 Debian, Exim 2 Debian Linux, Exim 2024-11-21 N/A
The receive_msg function in receive.c in the SMTP daemon in Exim 4.88 and 4.89 allows remote attackers to execute arbitrary code or cause a denial of service (use-after-free) via vectors involving BDAT commands.
CVE-2017-1000369 2 Debian, Exim 2 Debian Linux, Exim 2024-11-21 4.0 Medium
Exim supports the use of multiple "-p" command line arguments which are malloc()'ed and never free()'ed, used in conjunction with other issues allows attackers to cause arbitrary code execution. This affects exim version 4.89 and earlier. Please note that at this time upstream has released a patch (commit 65e061b76867a9ea7aeeb535341b790b90ae6c21), but it is not known if a new point release is available that addresses this issue at this time.
CVE-2016-9963 3 Canonical, Debian, Exim 3 Ubuntu Linux, Debian Linux, Exim 2024-11-21 N/A
Exim before 4.87.1 might allow remote attackers to obtain the private DKIM signing key via vectors related to log files and bounce messages.
