public via http://curl.haxx.se/docs/adv_20150422B.html Negotiate not treated as connection-oriented ============================================ Project cURL Security Advisory, April 22nd 2015 - [Permalink](http://curl.haxx.se/docs/adv_20150422B.html) VULNERABILITY ------------- libcurl keeps a pool of its last few connections around after use to fascilitate easy, conventient and completely transparent connection re-use for applications. When doing HTTP requests Negotiate authenticated, the entire connnection may become authenticated and not just the specific HTTP request which is otherwise how HTTP works, as Negotiate can basically use NTLM under the hood. curl was not adhering to this fact but would assume that such requests would also be authenticated per request. The net effect is that libcurl may end up re-using an authenticated Negotiate connection and sending subsequent requests on it using new credentials, while the connection remains authenticated with a previous initial credentials setup. We are not aware of any exploits of this flaw. INFO ---- This flaw can also affect the curl command line tool if a similar operation series is made with that. The Common Vulnerabilities and Exposures (CVE) project has assigned the name CVE-2015-3148 to this issue. AFFECTED VERSIONS ----------------- - Affected versions: from libcurl 7.10.6 to and including 7.41.0 - Not affected versions: libcurl >= 7.42.0 libcurl is used by many applications, but not always advertised as such! THE WORK-AROUND --------------- libcurl 7.42.0 closes Negotiate connections after they're done, effectively preventing wrongful re-use. We decided to do this blunt short-term fix to avoid this current problem and then continue to work on a better fix. A patch for this problem is available at: http://curl.haxx.se/CVE-2015-3148.patch RECOMMENDATIONS --------------- We suggest you take one of the following actions immediately, in order of preference: A - Upgrade to curl and libcurl 7.42.0 B - Apply the patch and rebuild libcurl C - Avoid using Negotiate with libcurl TIME LINE --------- It was first reported to the curl project on March 31 2015. We contacted distros@openwall on April 18. libcurl 7.42.0 was released on April 22nd 2015, coordinated with the publication of this advisory. CREDITS ------- Reported by Isaac Boukris Thanks a lot!
