EulerOS Virtualization 2.5.1 : kernel (EulerOS-SA-2018-1261)

high Nessus Plugin ID 117570

Synopsis

The remote EulerOS Virtualization host is missing multiple security updates.

Description

According to the versions of the kernel packages installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :

- A vulnerability was found in the Linux kernel's kernel/events/core.c:perf_cpu_time_max_percent_handler( ) function. Local privileged users could exploit this flaw to cause a denial of service due to integer overflow or possibly have unspecified other impact.(CVE-2017-18255)

- The code in the drivers/scsi/libsas/sas_scsi_host.c file in the Linux kernel allow a physically proximate attacker to cause a memory leak in the ATA command queue and, thus, denial of service by triggering certain failure conditions.(CVE-2018-10021)

- The kernel_wait4 function in kernel/exit.c in the Linux kernel, when an unspecified architecture and compiler is used, might allow local users to cause a denial of service by triggering an attempted use of the -INT_MIN value.(CVE-2018-10087)

- A an integer overflow vulnerability was discovered in the Linux kernel, from version 3.4 through 4.15, in the drivers/gpu/drm/udl/udl_fb.c:udl_fb_mmap() function. An attacker with access to the udldrmfb driver could exploit this to obtain full read and write permissions on kernel physical pages, resulting in a code execution in kernel space.(CVE-2018-8781)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected kernel packages.
