Debian DLA-883-1 : curl security update

low Nessus Plugin ID 99188

Synopsis

The remote Debian host is missing a security update.

Description

It was discovered that there was a buffer read overrun vulnerability in curl, a tool for downloading files from the internet, etc.

If a '%' ended the --write-out parameter, the string's 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 'Wheezy', 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.

Solution

Upgrade the affected packages.
