Exim 4 before 4.94.2 is affected by an Out-of-bounds Write in main() when setuid root, due to copying the CWD pathname into a too-small buffer on some platforms, enabling local privilege escalation. Affected products include Exim; advisories from Astra Linux, Alpine Linux, Debian, and others indi...

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-2020-28008

CVE-2020-28008 affects Exim 4 before 4.94.2. The vulnerability allows local privilege escalation via a crafted recipient address that indirectly leads to command execution because Exim operates as root in the spool directory (owned by a non-root user) and an attacker can write to a /var/spool/exi...

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...

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...
