SynopsisThe remote EulerOS Virtualization for ARM 64 host is missing multiple security updates.
DescriptionAccording to the versions of the kernel packages installed, the EulerOS Virtualization for ARM 64 installation on the remote host is affected by the following vulnerabilities :
- The kernel package contains the Linux kernel (vmlinuz), the core of any Linux operating system. The kernel handles the basic functions of the operating system:
memory allocation, process allocation, device input and output, etc.Security Fix(es):An issue was discovered in the Linux kernel before 4.20. There is a race condition in smp_task_timedout() and smp_task_done() in drivers/scsi/libsas/sas_expander.c, leading to a use-after-free.(CVE-2018-20836)The Linux kernel before 4.8 allows local users to bypass ASLR on setuid programs (such as /bin/su) because install_exec_creds() is called too late in load_elf_binary() in fs/binfmt_elf.c, and thus the ptrace_may_access() check has a race condition when reading /proc/pid/stat.(CVE-2019-11190)The Siemens R3964 line discipline driver in drivers/tty_r3964.c in the Linux kernel before 5.0.8 has multiple race conditions.(CVE-2019-11486)The Linux kernel before 5.1-rc5 allows page-i1/4z_refcount reference count overflow, with resultant use-after-free issues, if about 140 GiB of RAM exists. This is related to fs/fuse/dev.c, fs/pipe.c, fs/splice.c, include/linux/mm.h, include/linux/pipe_fs_i.h, kernel/trace/trace.c, mm/gup.c, and mm/hugetlb.c. It can occur with FUSE requests.(CVE-2019-11487)The coredump implementation in the Linux kernel before 5.0.10 does not use locking or other mechanisms to prevent vma layout or vma flags changes while it runs, which allows local users to obtain sensitive information, cause a denial of service, or possibly have unspecified other impact by triggering a race condition with mmget_not_zero or get_task_mm calls.
This is related to fs/userfaultfd.c, mm/mmap.c, fs/proc/task_mmu.c, and drivers/infiniband/core/uverbs_main.c.(CVE-2019-11599)A n issue was discovered in the Linux kernel before 5.0.7. A NULL pointer dereference can occur when megasas_create_frame_pool() fails in megasas_alloc_cmds() in drivers/scsi/megaraid/megaraid_sas_base.c. This causes a Denial of Service, related to a use-after-free.(CVE-2019-11810)In the tun subsystem in the Linux kernel before 4.13.14, dev_get_valid_name is not called before register_netdevice. This allows local users to cause a denial of service (NULL pointer dereference and panic) via an ioctl(TUNSETIFF) call with a dev name containing a / character. This is similar to CVE-2013-4343.(CVE-2018-7191)net/ipv6etfilterf_conntrac k_reasm.c in the Linux kernel before 2.6.34, when the nf_conntrack_ipv6 module is enabled, allows remote attackers to cause a denial of service (NULL pointer dereference and system crash) via certain types of fragmented IPv6 packets.(CVE-2012-2744)Heap-based buffer overflow in the udf_load_logicalvol function in fs/udf/super.c in the Linux kernel before 3.4.5 allows remote attackers to cause a denial of service (system crash) or possibly have unspecified other impact via a crafted UDF filesystem.(CVE-2012-3400)The mmc_ioctl_cdrom_read_data function in drivers/cdrom/cdrom.c in the Linux kernel through 3.10 allows local users to obtain sensitive information from kernel memory via a read operation on a malfunctioning CD-ROM drive.(CVE-2013-2164)The (1) get_user and (2) put_user API functions in the Linux kernel before 3.5.5 on the v6k and v7 ARM platforms do not validate certain addresses, which allows attackers to read or modify the contents of arbitrary kernel memory locations via a crafted application, as exploited in the wild against Android devices in October and November 2013.(CVE-2013-6282)The sctp_sf_do_5_2_4_dupcook function in net/sctp/sm_statefuns.c in the SCTP implementation in the Linux kernel before 3.8.5 does not properly handle associations during the processing of a duplicate COOKIE ECHO chunk, which allows remote attackers to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact via crafted SCTP traffic.(CVE-2013-2206)A elevation of privilege vulnerability in the Broadcom wi-fi driver. Product:
Android. Versions: Android kernel. Android ID:
A-37351060. References: B-V2017060101.(CVE-2017-0786)An issue was discovered in the Linux kernel before 5.0.4.
There is a use-after-free upon attempted read access to /proc/ioports after the ipmi_si module is removed, related to drivers/char/ipmi/ipmi_si_intf.c, drivers/char/ipmi/ipmi_si_mem_io.c, and drivers/char/ipmi/ipmi_si_port_io.c.(CVE-2019-11811)Not e1: kernel-4.19.36-vhulk1907.1.0.h529 and earlier versions in EulerOS Virtualization for ARM 64 188.8.131.52 return incorrect time information when executing the uname -a command.Note2: The kernel version number naming format has been changed after 4.19.36-1.2.184.aarch64, the new version format is 4.19.36-vhulk1907.1.0.hxxx.aarch64, which may lead to false positives of this security advisory.
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.
SolutionUpdate the affected kernel packages.
