in curl, the library and command-line tool for transferring data over
the internet.

For Debian 8 'Jessie', this issue has been fixed in curl version
7.38.0-4+deb8u16.

We recommend that you upgrade your curl 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."
