Name of the Vulnerable Software and Affected Versions
mport versions prior to 2.7.8
Description
In the MidnightBSD Package Manager, directory assets handled as ASSET DIR or ASSET DIR OWNER MODE in the
libmport/bundle read install pkg.c file utilize path-based mport mkdirp(), ownership, and permission operations. A local attacker with the ability to modify part of the target installation tree can employ dot-dot traversal or substitute symlinks during a privileged package installation. This allows the attacker to cause directory creation or attribute changes to affect paths outside the intended package directories.Recommendations
Update to version 2.7.8.
