Critical vulnerability affects Linux Ubuntu and Freebsd systems

According to vulnerability testing specialists, a compression library enclosed by default in multiple Linux distributions (Ubuntu, Debian, Gentoo, Arch Linux, and FreeBSD among others) is affected with a vulnerability that, if exploited, might enable a hacker to execute malicious code on the targeted pc.

Although this library is part of Windows and macOS systems, the vulnerability doesn't seem to have an effect on these systems.

The affected library is Libarchive, designed to form and browse compressed files. in line with vulnerability testing specialists, this can be a toolkit that fulfills multiple functions associated with storage files, conjointly includes alternative Linux utilities (tar, cpio and cat), that is why it's used extensively on more than one software system.

Just a number of days ago details were released about the serious vulnerability affecting this library, uncovered beside the distribution of security updates for Libarchive.

Vulnerability testing specialists think about that not everything is unhealthy news, as Windows and macOS, the foremost standard operational systems, don't seem to be laid low with this flaw.

Specialists in vulnerability testing from the International Institute of Cyber Security (IICS) mention that to this point there are no reports of active exploitation of this vulnerability; equally, an indication of thought isn't however developed, though it may well be a matter of hours for this to happen.
