CVE-2017-7500 is a high-severity vulnerability rated 7.3/10 on the CVSS scale. It was found that rpm did not properly handle RPM installations when a destination path was a symbolic link to a directory, possibly changing ownership and permissions of an arbitrary directory, and RPM files being placed in an arbitrary destination. An attacker, with write access to a directory in which a subdirectory will be installed, could redirect that directory to an arbitrary location and gain root privilege.. EPSS estimates a 0.41% chance of exploitation in the next 30 days.
