Kodi is a free and open source media-center and entertainment hub previously known as XBMC.
Kodi is vulnerable due to shipping with an embedded version of UnRAR. Please review the referenced CVE identifier for details.
A remote attacker, by enticing a user to process a specifically crafted RAR file, could execute arbitrary code.
There is no known workaround at this time.
All Kodi users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=media-tv/kodi-17.3-r1"
