Andrey Labunets of Facebook discovered that cURL, an URL transfer library, fails to properly handle URLs with embedded end-of-line characters. An attacker able to make an application using libcurl to access a specially crafted URL via an HTTP proxy could use this flaw to do additional requests in a way that was not intended, or insert additional request headers into the request. For the stable distribution (wheezy), this problem has been fixed in version 7.26.0-1+wheezy12. For the upcoming stable distribution (jessie), this problem will be fixed soon. For the unstable distribution (sid), this problem has been fixed in version 7.38.0-4. We recommend that you upgrade your curl packages.
