| CVE-2020-28017 | — | < 4.94.2-4.2 | 4.94.2-4.2 | May 6, 2021 | 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 | — | < 4.94.2-4.2 | 4.94.2-4.2 | May 6, 2021 | 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 | — | < 4.94.2-4.2 | 4.94.2-4.2 | May 6, 2021 | 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 | — | < 4.94.2-4.2 | 4.94.2-4.2 | May 6, 2021 | 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 | — | < 4.94.2-4.2 | 4.94.2-4.2 | May 6, 2021 | 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 | — | < 4.94.2-4.2 | 4.94.2-4.2 | May 6, 2021 | 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 | — | < 4.94.2-4.2 | 4.94.2-4.2 | May 6, 2021 | 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 | — | < 4.94.2-4.2 | 4.94.2-4.2 | May 6, 2021 | 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 | — | < 4.94.2-4.2 | 4.94.2-4.2 | May 6, 2021 | 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 day | ||
| CVE-2020-28008 | — | < 4.94.2-4.2 | 4.94.2-4.2 | May 6, 2021 | 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 com | ||
| CVE-2020-28007 | — | < 4.94.2-4.2 | 4.94.2-4.2 | May 6, 2021 | 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 | — | < 4.94.2-4.2 | 4.94.2-4.2 | May 11, 2020 | 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-2020-8015 | — | < 4.94.2-4.2 | 4.94.2-4.2 | Apr 2, 2020 | A UNIX Symbolic Link (Symlink) Following vulnerability in the packaging of exim in openSUSE Factory allows local attackers to escalate from user mail to root. This issue affects: openSUSE Factory exim versions prior to 4.93.0.4-3.1. | ||
| CVE-2019-16928 | — | KEV | < 4.94.2-4.2 | 4.94.2-4.2 | Sep 27, 2019 | 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. | |
