CVE-2005-0403: Red Hat Enterprise Linux
High severity, CVSS 7.2. EPSS: 0.4% chance of exploitation in the next 30 days.
init_dev in tty_io.c in the Red Hat backport of NPTL to Red Hat Enterprise Linux 3 does not properly clear controlling tty's in multi-threaded applications, which allows local users to cause a denial of service (crash) and possibly gain tty access via unknown attack vectors that trigger an access of a pointer to a freed structure.
