SynopsisThe remote Debian host is missing a security-related update.
DescriptionYamada Yasuharu discovered that cURL, an URL transfer library, is vulnerable to expose potentially sensitive information when doing requests across domains with matching tails. Due to a bug in the tailmatch function when matching domain names, it was possible that cookies set for a domain 'ample.com' could accidentally also be sent by libcurl when communicating with 'example.com'.
Both curl the command line tool and applications using the libcurl library are vulnerable.
SolutionUpgrade the curl packages.
For the stable distribution (squeeze), this problem has been fixed in version 7.21.0-2.1+squeeze3.
