It was discovered that there was a buffer read overrun vulnerability in curl, a tool for downloading files from the internet, etc.
If a โ%โ ended the --write-out parameter, the stringโs trailing NUL would be skipped and memory past the end of the buffer could be accessed and potentially displayed as part of the output.
For Debian 7 โWheezyโ, this issue has been fixed in curl version 7.26.0-1+wheezy18+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.
