Kategorie: | Huawei EulerOS Local Security Checks |
Titel: | Huawei EulerOS: Security Advisory for kernel (EulerOS-SA-2019-1244) |
Zusammenfassung: | The remote host is missing an update for the Huawei EulerOS 'kernel' package(s) announced via the EulerOS-SA-2019-1244 advisory. |
Beschreibung: | Summary: The remote host is missing an update for the Huawei EulerOS 'kernel' package(s) announced via the EulerOS-SA-2019-1244 advisory. Vulnerability Insight: A flaw was found In the Linux kernel, through version 4.19.6, where a local user could exploit a use-after-free in the ALSA driver by supplying a malicious USB Sound device (with zero interfaces) that is mishandled in usb_audio_probe in sound/usb/card.c. An attacker could corrupt memory and possibly escalate privileges if the attacker is able to have physical access to the system.(CVE-2018-19824) It was found that the Linux kernel can hit a BUG_ON() statement in the __xfs_get_blocks() in the fs/xfs/xfs_aops.c because of a race condition between direct and memory-mapped I/O associated with a hole in a file that is handled with BUG_ON() instead of an I/O failure. This allows a local unprivileged attacker to cause a system crash and a denial of service.(CVE-2016-10741) A division-by-zero in set_termios(), when debugging is enabled, was found in the Linux kernel. When the [io_ti] driver is loaded, a local unprivileged attacker can request incorrect high transfer speed in the change_port_settings() in the drivers/usb/serial/io_ti.c so that the divisor value becomes zero and causes a system crash resulting in a denial of service.(CVE-2017-18360) Since Linux kernel version 3.2, the mremap() syscall performs TLB flushes after dropping pagetable locks. If a syscall such as ftruncate() removes entries from the pagetables of a task that is in the middle of mremap(), a stale TLB entry can remain for a short time that permits access to a physical page after it has been released back to the page allocator and reused.(CVE-2018-18281) A use-after-free flaw can occur in the Linux kernel due to a race condition between packet_do_bind() and packet_notifier() functions called for an AF_PACKET socket. An unprivileged, local user could use this flaw to induce kernel memory corruption on the system, leading to an unresponsive system or to a crash. Due to the nature of the flaw, privilege escalation cannot be fully ruled out.(CVE-2018-18559) Affected Software/OS: 'kernel' package(s) on Huawei EulerOS Virtualization 2.5.3. Solution: Please install the updated package(s). CVSS Score: 6.8 CVSS Vector: AV:N/AC:M/Au:N/C:P/I:P/A:P |
