Debian DSA-3122-1 : curl - security update
Medium Nessus Plugin ID 80421
SynopsisThe remote Debian host is missing a security-related update.
DescriptionAndrey 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.
SolutionUpgrade the curl packages.
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.
