libcurl GnuTLS insufficient cert verification Vulnerability
===========================================================
Project cURL Security Advisory, July 10th 2007
http://curl.haxx.se/docs/security.html
1. VULNERABILITY
libcurl (when built to use GnuTLS) fails to verify that a peer's certificate
hasn't already expired or hasn't yet become valid. This allows malicious
servers to present certificates to libcurl that won't be rejected properly.
Notably, the cacert and common name checks are still in place which reduces
the risk for random servers to take advantage of this flaw.
There is no known exploit at the time of this writing.
The Common Vulnerabilities and Exposures (CVE) project has assigned the name
CVE-2007-3564 to this issue.
2. AFFECTED VERSIONS
Affected versions: curl and libcurl 7.14.0 to and including 7.16.3
Not affected versions: curl and libcurl 7.13.2 and earlier, 7.16.4 and later
Note that libcurl needs to be built to use GnuTLS for this flaw to be in
effect.
Also note that (lib)curl is used by many applications, and not always
advertised as such.
3. RECOMMENDATIONS
We suggest you take one of the following actions immediately, in order of
preference:
I - Upgrade to curl and libcurl 7.16.4
II - Apply the patch http://curl.haxx.se/libcurl-gnutlscert.patch to your
libcurl version and install this
III - Build curl with SSL provided by another library, like OpenSSL or NSS
IV - Build curl with SSL disabled
4. TIME LINE
We were notified by Kees Cook on June 27th, 2007. His notification email
contained a valid patch.
We agreed on and coordinated the synchronous disclosure of this problem
together with the curl 7.16.4 release.
curl 7.16.4 was released on July 10 2007, just before this flaw was publicly
disclosed.
