Aliases:
CVE-2017-16944
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.

4.93-13ubuntu1.5
Affected by 0 other vulnerabilities.
VCID-97g7-zfqp-aaag
Aliases:
CVE-2017-1000369
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-2020-28026
Exim 4 before 4.94.2 has Improper Neutralization of Line Delimiters, relevant in non-default configurations that enable Delivery Status Notification (DSN). Certain uses of ORCPT= can place a newline into a spool header file, and indirectly allow unauthenticated remote attackers to execute arbitrary commands as root.
4.93-13ubuntu1.5
Affected by 0 other vulnerabilities.
VCID-dar1-s72w-aaap
Aliases:
CVE-2020-28012
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.
4.93-13ubuntu1.5
Affected by 0 other vulnerabilities.
VCID-e6jv-9x6c-aaad
Aliases:
CVE-2019-15846

VCID-f5fh-ps3p-aaah
Aliases:
CVE-2018-6789
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.

VCID-mgdw-3553-aaac
Aliases:
CVE-2019-10149
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.
4.90.1-1ubuntu1.2
Affected by 23 other vulnerabilities.
VCID-ms2c-kqz5-aaas
Aliases:
CVE-2020-28017
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.
4.93-13ubuntu1.5
Affected by 0 other vulnerabilities.
VCID-nfxa-nhgz-aaaf
Aliases:
CVE-2020-28025
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.
4.93-13ubuntu1.5
Affected by 0 other vulnerabilities.
VCID-qsmb-2g7v-aaar
Aliases:
CVE-2021-27216
Exim 4 before 4.94.2 has Execution with Unnecessary Privileges. By leveraging a delete_pid_file race condition, a local user can delete arbitrary files as root. This involves the -oP and -oPX options.
4.93-13ubuntu1.5
Affected by 0 other vulnerabilities.
VCID-qzhj-an3g-aaag
Aliases:
CVE-2020-28010
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).
4.93-13ubuntu1.5
Affected by 0 other vulnerabilities.
VCID-r8gu-yzg5-aaad
Aliases:
CVE-2016-9963
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.
4.82-3ubuntu2.2
Affected by 28 other vulnerabilities.
4.86.2-2ubuntu2.1
Affected by 28 other vulnerabilities.
VCID-rq3j-uyp1-aaah
Aliases:
CVE-2020-28009
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).
4.93-13ubuntu1.5
Affected by 0 other vulnerabilities.
VCID-s3gk-53vt-aaak
Aliases:
CVE-2014-2972
expand.c in Exim before 4.83 expands mathematical comparisons twice, which allows local users to gain privileges and execute arbitrary commands via a crafted lookup value.
4.82-3ubuntu2.1
Affected by 29 other vulnerabilities.
VCID-v8mn-cp7h-aaaf
Aliases:
CVE-2020-28023
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.
4.93-13ubuntu1.5
Affected by 0 other vulnerabilities.
VCID-v8uj-dynt-aaad
Aliases:
CVE-2020-12783
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.
4.92.1-1ubuntu3.1
Affected by 20 other vulnerabilities.
4.93-13ubuntu1.1
Affected by 19 other vulnerabilities.
VCID-v95c-2sp9-aaan
Aliases:
CVE-2020-28008
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.
4.93-13ubuntu1.5
Affected by 0 other vulnerabilities.
VCID-v9dw-pa2e-aaaa
Aliases:
CVE-2020-28013
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.
4.93-13ubuntu1.5
Affected by 0 other vulnerabilities.
VCID-w3f9-2bds-aaah
Aliases:
CVE-2020-28019
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.
4.93-13ubuntu1.5
Affected by 0 other vulnerabilities.
VCID-w8z8-chwq-aaap
Aliases:
CVE-2020-28007
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.
4.93-13ubuntu1.5
Affected by 0 other vulnerabilities.
VCID-zd9g-egsv-aaap
Aliases:
CVE-2020-28024
Exim 4 before 4.94.2 allows Buffer Underwrite that may result in unauthenticated remote attackers executing arbitrary commands, because smtp_ungetc was only intended to push back characters, but can actually push back non-character error codes such as EOF.
4.93-13ubuntu1.5
Affected by 0 other vulnerabilities.
