CVSS: 6.1EPSS: 0%CPEs: 7EXPL: 0CVE-2018-16658 – kernel: Information leak in cdrom_ioctl_drive_status
https://notcve.org/view.php?id=CVE-2018-16658
An issue was discovered in the Linux kernel before 4.18.6. An information leak in cdrom_ioctl_drive_status in drivers/cdrom/cdrom.c could be used by local attackers to read kernel memory because a cast from unsigned long to int interferes with bounds checking. This is similar to CVE-2018-10940. Se ha descubierto un problema en el kernel de Linux hasta antes de la versión 4.18.6. Una fuga de información en cdrom_ioctl_drive_status en drivers/cdrom/cdrom.c podría ser empleada por atacantes locales para leer memoria del kernel debido a que una conversión de un long no firmado a int interfiere con la comprobación de límites. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=8f3fafc9c2f0ece10832c25f7ffcb07c97a32ad4 http://www.securityfocus.com/bid/105334 https://access.redhat.com/errata/RHSA-2019:2029 https://access.redhat.com/errata/RHSA-2019:2043 https://access.redhat.com/errata/RHSA-2019:4154 https://cdn.kernel.org/pub/linux/kernel/v4.x/ChangeLog-4.18.6 https://github.com/torvalds/linux/commit/8f3fafc9c2f0ece10832c25f7ffcb07c97a32ad4 https://lists.debian.org/debian-lts-announce/2018/10/ • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •

Memory leak in the irda_bind function in net/irda/af_irda.c and later in drivers/staging/irda/net/af_irda.c in the Linux kernel before 4.17 allows local users to cause a denial of service (memory consumption) by repeatedly binding an AF_IRDA socket. Fuga de memoria en la función irda_bind en net/irda/af_irda.c y siguientes en drivers/staging/irda/net/af_irda.c en el kernel de Linux en versiones anteriores a la 4.17 permite que usuarios locales provoquen una denegación de servicio (consumo de memoria) enlazando repetidamente un socket AF_IRDA. • http://www.securityfocus.com/bid/105302 https://lists.debian.org/debian-lts-announce/2018/10/msg00003.html https://lists.debian.org/debian-lts-announce/2019/03/msg00017.html https://usn.ubuntu.com/3775-1 https://usn.ubuntu.com/3775-2 https://usn.ubuntu.com/3776-1 https://usn.ubuntu.com/3776-2 https://usn.ubuntu.com/3777-1 https://usn.ubuntu.com/3777-2 https://usn.ubuntu.com/3777-3 https://www.debian.org/security/2018/dsa-4308 https://www • CWE-400: Uncontrolled Resource Consumption CWE-772: Missing Release of Resource after Effective Lifetime •

The irda_setsockopt function in net/irda/af_irda.c and later in drivers/staging/irda/net/af_irda.c in the Linux kernel before 4.17 allows local users to cause a denial of service (ias_object use-after-free and system crash) or possibly have unspecified other impact via an AF_IRDA socket. La función irda_setsockopt en net/irda/af_irda.c y siguientes en drivers/staging/irda/net/af_irda.c en el kernel de Linux en versiones anteriores a la 4.17 permite que usuarios locales provoquen una denegación de servicio (uso de memoria previamente liberada en ias_object y cierre inesperado del sistema) o cualquier otro tipo de impacto sin especificar mediante un socket AF_IRDA. • http://www.securityfocus.com/bid/105304 https://lists.debian.org/debian-lts-announce/2018/10/msg00003.html https://usn.ubuntu.com/3775-1 https://usn.ubuntu.com/3775-2 https://usn.ubuntu.com/3776-1 https://usn.ubuntu.com/3776-2 https://usn.ubuntu.com/3777-1 https://usn.ubuntu.com/3777-2 https://usn.ubuntu.com/3777-3 https://www.debian.org/security/2018/dsa-4308 https://www.spinics.net/lists/stable/msg255031.html https://www.spinics.net/lists • CWE-416: Use After Free •

An issue was discovered in yurex_read in drivers/usb/misc/yurex.c in the Linux kernel before 4.17.7. Local attackers could use user access read/writes with incorrect bounds checking in the yurex USB driver to crash the kernel or potentially escalate privileges. Se descubrió un problema en yurex_read en drivers/usb/misc/yurex.c en el kernel de Linux hasta la versión 4.17.7. Los atacantes locales pueden emplear lecturas/escrituras de acceso de usuario con una comprobación incorrecta de límites en el controlador USB yurex para provocar el cierre inesperado del kernel o escalar privilegios. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=f1e255d60ae66a9f672ff9a207ee6cd8e33d2679 https://bugzilla.suse.com/show_bug.cgi?id=1106095 https://bugzilla.suse.com/show_bug.cgi?id=1115593 https://cdn.kernel.org/pub/linux/kernel/v4.x/ChangeLog-4.17.7 https://github.com/torvalds/linux/commit/f1e255d60ae66a9f672ff9a207ee6cd8e33d2679 https://lists.debian.org/debian-lts-announce/2018/10/msg00003.html https://usn.ubuntu.com/3776-1 https://usn.ubuntu.com/3776-2 https • CWE-787: Out-of-bounds Write •

A flaw was found in the Linux kernel present since v4.0-rc1 and through v4.13-rc4. A crafted network packet sent remotely by an attacker may force the kernel to enter an infinite loop in the cipso_v4_optptr() function in net/ipv4/cipso_ipv4.c leading to a denial-of-service. A certain non-default configuration of LSM (Linux Security Module) and NetLabel should be set up on a system before an attacker could leverage this flaw. Se ha detectado un error en el kernel de Linux presente desde v4.0-rc1 y hasta v4.13-rc4. Un paquete de red manipulado enviado de forma remota por un atacante podría forzar al kernel a entrar en un bucle infinito en la función cipso_v4_optptr() en net/ipv4/cipso_ipv4.c, lo que conduce a una denegación de servicio (DoS). • http://seclists.org/oss-sec/2018/q3/179 http://www.securityfocus.com/bid/105154 http://www.securitytracker.com/id/1041569 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2018-10938 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=40413955ee265a5e42f710940ec78f5450d49149 https://lists.debian.org/debian-lts-announce/2018/10/msg00003.html https://usn.ubuntu.com/3797-1 https://usn.ubuntu.com/3797-2 https://www.debian.org/security/2018/dsa-4308 • CWE-835: Loop with Unreachable Exit Condition ('Infinite Loop') •
