CVSS 3.0
7.5 highCVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:NCVE-2019-13173
High (7.5) in fstream project fstream. EPSS 2.4% chance of exploitation in the next 30 days. Fixed in fstream 1.0.12.
fstream before 1.0.12 is vulnerable to Arbitrary File Overwrite. Extracting tarballs containing a hardlink to a file that already exists in the system, and a file that matches the hardlink, will overwrite the system's file with the contents of the extracted file. The fstream.DirWriter() function is vulnerable.
