+++ 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 http://linux.bkbits.net:8080/linux-2.6/cset@43b729ad5Zc6t6URyaHNNtodT1nRpg 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)
