libarchive can let attackers write any file

CVE-2015-2304 · published 11 years ago
Summary

The libarchive library (used in Ubuntu Linux and openSUSE) lets a specially crafted archive specify full file paths, allowing a remote attacker to create or overwrite files anywhere on the system. This could let them install malicious code or tamper with important data. Update libarchive to the latest version or apply the vendor’s security patch to stop the issue.
