Denial of service via ERF gen_time over-read

Buffer over-read in the ERF file parser in Wireshark 4.6.0 through 4.6.7 and 4.4.0 through 4.4.17 allows remote attackers to crash the application via a malformed capture file. The ERF metadata parser accepts a short gen_time tag at the end of a record, then populate_summary_info copies eight bytes from tag.value without verifying that the tag actually contains eight value bytes, causing an out-of-bounds read past the record buffer. Exploitation requires convincing a user to open a crafted ERF capture file in Wireshark or a bundled reader such as TShark, Capinfos, or Editcap, and the published impact is limited to application crash or abnormal termination.
