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-2020-28010 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-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-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.
CVE-2020-28009 1 Exim 1 Exim 2021-05-10 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-2020-28011 1 Exim 1 Exim 2021-05-10 7.2 HIGH 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-2020-28013 1 Exim 1 Exim 2021-05-10 7.2 HIGH 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-2020-28016 1 Exim 1 Exim 2021-05-10 7.2 HIGH 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 2021-05-10 7.2 HIGH 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-2020-28019 1 Exim 1 Exim 2021-05-10 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-2020-28021 1 Exim 1 Exim 2021-05-10 9.0 HIGH 8.8 HIGH
Exim 4 before 4.94.2 has Improper Neutralization of Line Delimiters. An authenticated remote SMTP client can insert newline characters into a spool file (which indirectly leads to remote code execution as root) via AUTH= in a MAIL FROM command.
CVE-2020-28023 1 Exim 1 Exim 2021-05-10 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-2020-28025 1 Exim 1 Exim 2021-05-10 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-2020-12783 1 Exim 1 Exim 2021-05-04 5.0 MEDIUM 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-2017-16944 2 Debian, Exim 2 Debian Linux, Exim 2021-05-04 5.0 MEDIUM 7.5 HIGH
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-2020-8015 2 Exim, Opensuse 2 Exim, Opensuse 2020-11-20 7.2 HIGH 7.8 HIGH
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-2016-1531 1 Exim 1 Exim 2017-09-08 6.9 MEDIUM 7.0 HIGH
Exim before 4.86.2, when installed setuid root, allows local users to gain privileges via the perl_startup argument.
