V X.Org v libX11 do 1.8.7 a libXpm do 3.5.17 bylo nalezeno a v upstreamu opraveno 5 bezpečnostních chyb (CVE-2023-43785, CVE-2023-43786, CVE-2023-43787, CVE-2023-43788 a CVE-2023-43789). Dvě nejstarší jsou s námi 35 let. Obsaženy byly již v X11R2 vydaném v únoru 1988.
Byly publikovány informace o bezpečnostní chybě Looney Tunables aneb CVE-2023-4911 v glibc ld.so. Útočník ji může využít k lokální eskalaci práv. Vyzkoušeno na výchozích instalacích linuxových distribucí Fedora 37 a 38, Ubuntu 22.04 a 23.04 a Debian 12 a 13. Chyba byla do glibc zavlečena v dubnu 2021. Detaily v txt.
Na Kickstarteru byla spuštěna crowdfundingová kampaň na podporu telefonu Murena 2 s /e/OS. Telefon má 2 hardwarové přepínače. Prvním lze jednoduše vypnout kamery a mikrofony. Druhým se lze odpojit od sítí.

Ahoj,
To vypada ze je problem s filesystemem na md1, zkus znovu nabootovat z CD a pripojit ho nekam do adresare `mount /dev/md1 /mnt/nekam` a podivej se co obsahuje.
Souborovy system na md1 vypada dobre.

Tak to uz zbyva snad jen to ze by jsi v initrd nemel podporu pro raid, zkus ho znovu vytvorit a pridat tam potrebne moduly. Uz si nepamatuji jaky je na to v opensuse prikaz mkinitrd nebo tak nejak, ale bude to trochu slozitejsi. Nabootuj z cd udelej adresar treba /mnt/md1, pripoj do nej /dev/md1 a potom pomoc mount -o bind pripoj adresare /dev /proc a /sys do adresaru v /mnt/md1 (mount -o bind /proc /mnt/md1/proc) a nakonec udelej chroot /mnt/md1 . Tim se dostanes do systemu na md1 a muzes si zacit hrat s initrd.
ps. K cemu potrebujes pae? Mas vic jak 3GB RAM na 32bit masine?
To take nepomohlo. V initrd podpora pro raid je.

Vsiml jsem si, ze disky jsou docela velke. Nemuze mit system problem s nactenim initrd? Mel jsem nedavno podobny problem na HPw9400 (asi) s 300MB disky a byl to urcite problem BIOS a grubu. Zkuste dat adresar /boot na misto swapu a samozrejme upravit podle toho grub i fstab. Nevnucuji vam toto reseni, samozrejme cokoli, kde adresar /boot je na prvnich cylindrech disku by mohlo stacit.
Samozrejme misto 300MB melo byt 300GB 
Zkousel jsem konfiguraci zmenit takhle:
sda1 swap
sdb1 /boot
md1 (sda2,sdb2) /
Ale to nijak nepomohlo
Teprve ted jsem si vsiml, ze kdyz za

$
napisu exit, dam enter tak bootovani pokracuje.
Ví někdo co s tím?
Takhle vypada /etc/fstab

/dev/md1 / ext3 defaults,acl,user_xattr 1 1Jeste muzes zkusit konec prepsat na 0 0, pak se filesystem nebude kontrolovat pri startu, treba to pomuze odhalit pricinu problemu. Potom doporucuju vratit zpet na 1 1. Sice se ti system snazi sestavit pole sam od sebe, ale vetsinou jsem videl ze je potreba jadru predat parametry: "md=0,/dev/sda1,/dev/sdb1 md=1,/dev/sda2,/dev/sdb2". Alespon v archu to tak musim napsat. Zdenek
