CVE-2017-7500 (GCVE-0-2017-7500)

Vulnerability from cvelistv5 – Published: 2018-08-13 17:00 – Updated: 2024-08-05 16:04

Summary

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.

Severity

7.3 (High)
