The remote Debian host is missing a security-related update.
Two vulnerabilities have been discovered in cURL, an URL transfer library. The Common Vulnerabilities and Exposures project identifies the following problems : - CVE-2014-0138 Steve Holme discovered that libcurl can in some circumstances re-use the wrong connection when asked to do transfers using other protocols than HTTP and FTP. - CVE-2014-0139 Richard Moore from Westpoint Ltd. reported that libcurl does not behave compliant to RFC 2828 under certain conditions and incorrectly validates wildcard SSL certificates containing literal IP addresses.
Upgrade the curl packages. For the oldstable distribution (squeeze), these problems have been fixed in version 7.21.0-2.1+squeeze8. For the stable distribution (wheezy), these problems have been fixed in version 7.26.0-1+wheezy9.
