CVE-2020-28007 log

Source
Severity Medium
Remote No
Type Arbitrary file overwrite
Description
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.
Group Package Affected Fixed Severity Status Ticket
