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...

CVE-2020-28018

Exim 4 before 4.94.2 is affected by a Use-After-Free in smtp_reset when TLS/OpenSSL is in use, enabling remote code execution via crafted TLS/SMTP sequences. The flaw centers on a freed gstring buffer in tls_write(), which can be referenced after smtp_reset frees pool memory, potentially leaking ...

CVE-2020-28017

Exim 4 before 4.94.2 allows Integer Overflow to Buffer Overflow in receiveaddrecipient via an e-mail message with fifty million recipients. NOTE: remote exploitation may be difficult because of resource consumption...

CVE-2020-28016

Exim 4 before 4.94.2 is affected by a heap/out-of-bounds write (off-by-two) caused by mishandling of -F '' in parse_fix_phrase. If exploiting, this could enable local/write conditions as outlined in CVE-2020-28016. The issue is fixed in Exim 4.94.2; upgrading to that version is the recommended re...

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

CVE-2020-28013 affects Exim 4 prior to 4.94.2, enabling a heap-based buffer overflow via mishandling of -F '.(' on the command line and negative sizes in strncpy. This may allow local privilege escalation from any user to root. The connected documents confirm the issue and indicate Exim 4.94.2 or...

CVE-2020-28012

CVE-2020-28012 affects Exim 4 prior to 4.94.2. The issue stems from rda_interpret using a privileged pipe that lacks a close-on-exec flag, exposing a file descriptor to an unintended control sphere. This could enable access to the FD by a local attacker and contribute to privilege/escalation vect...

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...

CVE-2020-28009

Exim 4 before 4.94.2 allows Integer Overflow to Buffer Overflow because getstdinput 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-2020-28009

Exim 4 before 4.94.2 is vulnerable to an Integer Overflow caused by get_stdinput reading unbounded input and growing a size variable, leading to a Buffer Overflow. The description notes exploitation may be impractical (days to overflow); no explicit exploit details are provided in the connected d...

CVE-2020-28007

Exim 4.x prior to 4.94.2 is affected by CVE-2020-28007, which allows local privilege escalation by exploiting a symlink/hard-link attack in the log directory where Exim runs as root and the directory is owned by a non-root user. The root-owned files can be overwritten from a local attacker, enabl...

PT-2021-28247

Name of the Vulnerable Software and Affected Versions: No specific software or versions are mentioned in the provided description. Description: The issue is related to a heap-use-after-free READ 4 crash type. The crash state involves functions such as cleanup live vars, zend cleanup unfinished...

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-2020-28016

Exim 4 before 4.94.2 allows an off-by-two Out-of-bounds Write because "-F ''" is mishandled by parsefixphrase...

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...

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...
