NVD Description

Note: Versions mentioned in the description apply only to the upstream wireshark package and not the wireshark package as distributed by Ubuntu.

The fragment_add_seq_common function in epan/reassemble.c in the ASN.1 BER dissector in Wireshark before r48943 has an incorrect pointer dereference during a comparison, which allows remote attackers to cause a denial of service (application crash) via a malformed packet.
