CVE-2016-4809: Input Validation
First published: Thu Jun 16 2016(Updated: )
A cpio archive with a ridiculously large symlink can cause memory allocation to fail, resulting in any attempt to view or extract the archive crashing. The failed allocation appears to be handled correctly within libarchive and not lead to further issues.
