It is recommended that administrators running tar check for an updated version of the software for their operating system. - --------------------------BEGIN INCLUDED TEXT-------------------- - -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 Package : tar Version : 1.27.1-2+deb8u2 CVE ID : CVE-2018-20482 Debian Bug : #917377 It was discovered that there was a potential denial of service vulnerability in tar, the GNU version of the tar UNIX archiving utility. The --sparse argument looped endlessly if the file shrank whilst it was being read. Tar would only break out of this endless loop if the file grew again to (or beyond) its original end of file. For Debian 8 "Jessie", this issue has been fixed in tar version 1.27.1-2+deb8u2. We recommend that you upgrade your tar packages.
