Debian DSA-3069-1 : curl - security update

medium Nessus Plugin ID 79065

Language:

Synopsis

The remote Debian host is missing a security-related update.

Description

Symeon Paraschoudis discovered that the curl_easy_duphandle() function in cURL, an URL transfer library, has a bug that can lead to libcurl eventually sending off sensitive data that was not intended for sending, while performing a HTTP POST operation.

This bug requires CURLOPT_COPYPOSTFIELDS and curl_easy_duphandle() to be used in that order, and then the duplicate handle must be used to perform the HTTP POST. The curl command line tool is not affected by this problem as it does not use this sequence.

Solution

Upgrade the curl packages.

For the stable distribution (wheezy), this problem has been fixed in version 7.26.0-1+wheezy11.

For the upcoming stable distribution (jessie), this problem will be fixed in version 7.38.0-3.
