CVE-2018-1050 – samba: NULL pointer dereference in printer server process
https://notcve.org/view.php?id=CVE-2018-1050
All versions of Samba from 4.0.0 onwards are vulnerable to a denial of service attack when the RPC spoolss service is configured to be run as an external daemon. Missing input sanitization checks on some of the input parameters to spoolss RPC calls could cause the print spooler service to crash. Todas las versiones de Samba, desde la 4.0.0 en adelante, son vulnerables a un ataque de denegación de servicio (DoS) cuando el servicio RPC spoolss se configura para ejecutarse como demonio externo. La falta de comprobaciones de saneamiento de entradas en algunos de los parámetros de entrada en las llamadas RPC spoolss podrían provocar que el servicio print spooler se cierre inesperadamente. A null pointer dereference flaw was found in Samba RPC external printer service. • http://www.securityfocus.com/bid/103387 http://www.securitytracker.com/id/1040493 https://access.redhat.com/errata/RHSA-2018:1860 https://access.redhat.com/errata/RHSA-2018:1883 https://access.redhat.com/errata/RHSA-2018:2612 https://access.redhat.com/errata/RHSA-2018:2613 https://access.redhat.com/errata/RHSA-2018:3056 https://bugzilla.redhat.com/show_bug.cgi?id=1538771 https://help.ecostruxureit.com/display/public/UADCE725/Security+fixes+in+StruxureWare+Data+Center+Expert+v7.6. • CWE-476: NULL Pointer Dereference •
CVE-2018-1057
https://notcve.org/view.php?id=CVE-2018-1057
On a Samba 4 AD DC the LDAP server in all versions of Samba from 4.0.0 onwards incorrectly validates permissions to modify passwords over LDAP allowing authenticated users to change any other users' passwords, including administrative users and privileged service accounts (eg Domain Controllers). En Samba 4 AD DC, el servidor LDAP en todas las versiones de Samba, desde la 4.0.0 en adelante, valida incorrectamente los permisos para modificar contraseñas por LDAP. Esto permite que usuarios autenticados cambien las contraseñas de cualquier otro usuario, incluyendo usuarios administrativos y cuentas de servicio privilegiadas (por ejemplo, Domain Controllers). • http://www.securityfocus.com/bid/103382 http://www.securitytracker.com/id/1040494 https://bugzilla.redhat.com/show_bug.cgi?id=1553553 https://lists.debian.org/debian-lts-announce/2019/04/msg00013.html https://security.gentoo.org/glsa/201805-07 https://security.netapp.com/advisory/ntap-20180313-0001 https://usn.ubuntu.com/3595-1 https://www.debian.org/security/2018/dsa-4135 https://www.samba.org/samba/security/CVE-2018-1057.html https://www.synology.com/support/security& • CWE-863: Incorrect Authorization •
CVE-2018-8087 – kernel: Memory leak in drivers/net/wireless/mac80211_hwsim.c:hwsim_new_radio_nl() can lead to potential denial of service
https://notcve.org/view.php?id=CVE-2018-8087
Memory leak in the hwsim_new_radio_nl function in drivers/net/wireless/mac80211_hwsim.c in the Linux kernel through 4.15.9 allows local users to cause a denial of service (memory consumption) by triggering an out-of-array error case. Fuga de memoria en la función hwsim_new_radio_nl en drivers/net/wireless/mac80211_hwsim.c en el kernel de Linux hasta la versión 4.15.9 permite que usuarios locales provoquen una denegación de servicio (consumo de memoria) desencadenando un caso de error fuera de array. The Linux kernel is vulnerable to a memory leak in the drivers/net/wireless/mac80211_hwsim.c:hwsim_new_radio_nl() function. An attacker could exploit this to cause a potential denial of service. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=0ddcff49b672239dda94d70d0fcf50317a9f4b51 http://www.securityfocus.com/bid/103397 https://access.redhat.com/errata/RHSA-2019:2029 https://access.redhat.com/errata/RHSA-2019:2043 https://github.com/torvalds/linux/commit/0ddcff49b672239dda94d70d0fcf50317a9f4b51 https://usn.ubuntu.com/3676-1 https://usn.ubuntu.com/3676-2 https://usn.ubuntu.com/3677-1 https://usn.ubuntu.com/3677-2 https://usn.ubuntu.com/3678-1 • CWE-400: Uncontrolled Resource Consumption CWE-772: Missing Release of Resource after Effective Lifetime •

CVE-2018-7858 – QEMU: cirrus: OOB access when updating VGA display
https://notcve.org/view.php?id=CVE-2018-7858
Quick Emulator (aka QEMU), when built with the Cirrus CLGD 54xx VGA Emulator support, allows local guest OS privileged users to cause a denial of service (out-of-bounds access and QEMU process crash) by leveraging incorrect region calculation when updating VGA display. Quick Emulator (también conocido como QEMU), cuando se integra con soporte para Cirrus CLGD 54xx VGA Emulator, permite que usuarios privilegiados locales, invitados del sistema operativo, provoquen una denegación de servicio (acceso fuera de límites y cierre inesperado del proceso QEMU) aprovechando los cálculos de región incorrectos al actualizar la pantalla VGA. • http://lists.opensuse.org/opensuse-security-announce/2019-03/msg00042.html http://www.openwall.com/lists/oss-security/2018/03/09/1 http://www.securityfocus.com/bid/103350 https://access.redhat.com/errata/RHSA-2018:1369 https://access.redhat.com/errata/RHSA-2018:1416 https://access.redhat.com/errata/RHSA-2018:2162 https://bugzilla.redhat.com/show_bug.cgi?id=1553402 https://lists.nongnu.org/archive/html/qemu-devel/2018-03/msg02174.html https://usn.ubuntu.com/3649-1 ht • CWE-125: Out-of-bounds Read •
