"It was discovered that there was an issue in the curl a command-line
tool for downloading (eg.) data over HTTP.

curl could have be tricked into reading data beyond the end of a heap
based buffer used to store downloaded content.

For more information, please see upstream's advisory at :

https://curl.haxx.se/docs/adv_2018-b138.html

For Debian 7 'Wheezy', this issue has been fixed in curl version
7.26.0-1+wheezy25+deb7u1.

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."
