pwlib, as used by Ekiga 2.0.5 and possibly other products, allows remote attackers to cause a denial of service (application crash) via a long argument to the PString::vsprintf function, related to a memory management flaw. NOTE: this issue was originally reported as being in the SIPURL::GetHostAddress function in Ekiga (formerly GnomeMeeting).
