- 漏洞讨论

'gnome-pty-helper' is susceptible to a local UTMP hostname spoofing vulnerability. This issue is due to the failure of the application to properly validate user-supplied data prior to using it to update UTMP records.

This vulnerability allows users to spoof remote hostname information in UTMP records. This may aid attackers by misdirecting administrators and users as to the correct origin of the attacker.
