Description Jan Lieskovsky 2011-06-02 09:42:38 UTC

It was found that Wireshark's DICOM dissector did not check for invalid
payload data unit length. A remote attacker could create a specially-crafted
capture file, which once opened, by a local, unsuspecting user could lead
to wireshark application hang / termination.
