Debian DSA-2713-1 : curl - heap overflow

medium Nessus Plugin ID 66974

Language:

Synopsis

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

Description

Timo Sirainen discovered that cURL, an URL transfer library, is prone to a heap overflow vulnerability due to bad checking of the input data in the curl_easy_unescape function.

The curl command line tool is not affected by this problem as it doesn't use the curl_easy_unescape function.

Solution

Upgrade the curl packages.

For the oldstable distribution (squeeze), this problem has been fixed in version 7.21.0-2.1+squeeze4.

For the stable distribution (wheezy), this problem has been fixed in version 7.26.0-1+wheezy3.
