I think only libpurple 2.7.6-2.7.8 are vulnerable because it was introduced by the MSN code remodelling that was merged in 2.7.6, not due to what the servers send. Regards, Stu. </end quote> Could you allocate a CVE id for this issue? Thanks && Regards, Jan. -- Jan iankko Lieskovsky / Red Hat Security Response Team
