CVE-2005-0839
HighSummary
A vulnerability in the Linux kernel 2.6 before version 2.6.11 allows a local user to gain elevated privileges by injecting mouse or keyboard events into other user sessions. The issue is due to missing access restrictions on the N_MOUSE line discipline for a TTY.
Risk Assessment
An attacker can take control of other users' sessions, leading to privilege escalation and potential compromise of system confidentiality and integrity.
Recommendation
Immediately update the kernel to version 2.6.11 or later, which includes a fix restricting access to the N_MOUSE discipline.
