Kure kure kusagadzikana muNetBSD kernel, yakashandiswa kubva kunetiweki yemuno

Pamusoro peNetBSD kubviswa vulnerability, zvichikonzerwa nekushaikwa kwekutarisa miganhu yebuffer paunenge uchigadzira jumbo mafuremu mumadhiraivha etiweki adapta akabatana kuburikidza ne USB. Nyaya iyi inokonzeresa kuti chikamu chepakiti chikopwe kupfuura buffer yakagoverwa mumbuf cluster, iyo inogona kushandiswa kuita kurwisa kodhi padanho rekernel nekutumira mafaera chaiwo kubva kunetiweki yenzvimbo. Gadziriso yekuvhara njodzi yakaburitswa muna Nyamavhuvhu 28, asi ruzivo rwedambudziko rwave kungoburitswa. Nyaya inobata atu, demo, demo, otus, run and ure drivers.

Zvichakadaro, muWindows TCP/IP stack kuzivikanwa kutsoropodza vulnerability, kubvumira kuita kure attacker code nekutumira ICMPv6 packet ine IPv6 router kushambadzira (RA, Router Advertisement).
Kunetseka anooneka Kubva Kuvandudza 1709 ye Windows 10/Windows Server 2019, iyo yakaunza tsigiro yekupfuura DNS configuration kuburikidza neICMPv6 RA packets, inotsanangurwa muRFC 6106. akadudzirwa seakawanda e16, izvo zvakatungamira kumatambudziko nekuparura uye kugoverwa kwe8 bytes kushoma ndangariro, sezvo mamwe 8 byte akaonekwa seanotevera ndima).
