Debian DLA-1623-1 : tar security update
Low Nessus Plugin ID 119957
SynopsisThe remote Debian host is missing a security update.
DescriptionIt 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.
NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
SolutionUpgrade the affected tar, and tar-scripts packages.
