Description Jan Lieskovsky 2013-04-10 12:54:29 UTC
A security flaw was found in the way the library of cURL, an utility for retrieval of files from remote servers, performed match of cookie domain names when making a decision if (previously stored cookies) should be sent to particular domain. Due to a bug in match function implementation, (formerly) the decision / match succeeded also in cases, where just suffix / certain part of the domain name matched the domain name, the current request originated from. A remote attacker could use this flaw to possibly hijack the user session of the victim by submitting a request containing a specially-crafted domain name.
