Detail

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.

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.

For the unstable distribution (sid), this problem has been fixed in version 7.31.0-1.

We recommend that you upgrade your curl packages.
