Summary
Arbitrary File Overwrite in fstream
Details

Versions of fstream prior to 1.0.12 are 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.

Recommendation

Upgrade to version 1.0.12 or later.

Severity ?
7.5 (High)
CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N
