CVE-2020-28020
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-2020-28014
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
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-2020-28008
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...
CVE-2020-28024
Exim 4 before 4.94.2 allows Buffer Underwrite that may result in unauthenticated remote attackers executing arbitrary commands, because smtpungetc was only intended to push back characters, but can actually push back non-character error codes such as EOF...
UBUNTU-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...
UBUNTU-CVE-2021-27216
Exim 4 before 4.94.2 has Execution with Unnecessary Privileges. By leveraging a deletepidfile race condition, a local user can delete arbitrary files as root. This involves the -oP and -oPX options...
UBUNTU-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...
UBUNTU-CVE-2020-28022
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
Exim 4 before 4.94.2 allows Use After Free in smtpreset in certain situations that may be common for builds with OpenSSL...
CVE-2020-28021
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...
UBUNTU-CVE-2020-28011
Exim 4 before 4.94.2 allows Heap-based Buffer Overflow in queuerun via two sender options: -R and -S. This may cause privilege escalation from exim to root...
