Description Mark J. Cox 2006-01-09 15:52:22 UTC
+++ This bug was initially created as a clone of Bug #177311 +++

CVE defines CVE-2005-4618 as:
"Buffer overflow in sysctl in the Linux Kernel 2.6 before 2.6.15 allows local
users to cause a denial of service and possibly execute arbitrary code via a
long string, which causes sysctl to write a zero byte outside the buffer."

This is fixed by

I can't see a useful attack vector here, writing a character to one spot after a
userland buffer seems to me likely at the worst to crash your userland program,
and not cause a DoS or privilege escalation.  So we have marked this severity
low but this could equally be severity none (kernel maintainers please let us
know what you think after analysis)
