Exim before 4.95 has a heap-based buffer overflow for the alias list in host_name_lookup in host.c when sender_host_name is set. | |||||
CVE-2022-3559 | 1 Exim | 1 Exim | 2024-02-04 | N/A | 7.5 HIGH |
A vulnerability was found in Exim and classified as problematic. This issue affects some unknown processing of the component Regex Handler. The manipulation leads to use after free. The name of the patch is 4e9ed49f8f12eb331b29bd5b6dc3693c520fddc2. It is recommended to apply a patch to fix this issue. The identifier VDB-211073 was assigned to this vulnerability. | |||||
CVE-2020-28023 | 1 Exim | 1 Exim | 2024-02-04 | 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-2020-28017 | 1 Exim | 1 Exim | 2024-02-04 | 7.5 HIGH | 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-2020-28019 | 1 Exim | 1 Exim | 2024-02-04 | 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-2020-28026 | 1 Exim | 1 Exim | 2024-02-04 | 9.3 HIGH | 9.8 CRITICAL |
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. | |||||
CVE-2020-28009 | 1 Exim | 1 Exim | 2024-02-04 | 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-2020-28013 | 1 Exim | 1 Exim | 2024-02-04 | 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-2020-28022 | 1 Exim | 1 Exim | 2024-02-04 | 7.5 HIGH | 9.8 CRITICAL |
Exim 4 before 4.94.2 has Improper Restriction of Write Operations within the Bounds of a Memory Buffer. This occurs when processing name=value pairs within MAIL FROM and RCPT TO commands. | |||||
CVE-2020-28018 | 1 Exim | 1 Exim | 2024-02-04 | 7.5 HIGH | 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-2021-27216 | 1 Exim | 1 Exim | 2024-02-04 | 6.3 MEDIUM | 6.3 MEDIUM |
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. | |||||
CVE-2020-28020 | 1 Exim | 1 Exim | 2024-02-04 | 7.5 HIGH | 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-2020-28015 | 1 Exim | 1 Exim | 2024-02-04 | 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-2020-28010 | 1 Exim | 1 Exim | 2024-02-04 | 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-2020-28008 | 1 Exim | 1 Exim | 2024-02-04 | 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-2020-28012 | 1 Exim | 1 Exim | 2024-02-04 | 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-2020-28011 | 1 Exim | 1 Exim | 2024-02-04 | 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-2020-28025 | 1 Exim | 1 Exim | 2024-02-04 | 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. |
