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 :
- drivers/soc/qcom/qdsp6v2/voice_svc.c in the QDSP6v2 Voice Service driver for the Linux kernel 3.x, as used in Qualcomm Innovation Center (QuIC) Android contributions for MSM devices and other products, allows attackers to cause a denial of service (memory corruption) or possibly have unspecified other impact via a write request, as demonstrated by a voice_svc_send_req buffer overflow.(CVE-2016-5343i1/4%0
- A use-after-free flaw was found in the way the Linux kernel's Advanced Linux Sound Architecture (ALSA) implementation handled user controls. A local, privileged user could use this flaw to crash the system.(CVE-2014-4655i1/4%0
- Race condition in the handle_to_path function in fs/fhandle.c in the Linux kernel through 3.19.1 allows local users to bypass intended size restrictions and trigger read operations on additional memory locations by changing the handle_bytes value of a file handle during the execution of this function.(CVE-2015-1420i1/4%0
- A flaw was found in the way the Linux kernel's keys subsystem handled the termination condition in the associative array garbage collection functionality. A local, unprivileged user could use this flaw to crash the system.(CVE-2014-3631i1/4%0
- A flaw was found in the ext4 subsystem. This vulnerability is a use after free vulnerability was found in __ext4_journal_stop(). Attackers could abuse this to allow any code which attempts to deal with the journal failure to be mishandled or not fail at all.
This could lead to data corruption or crashes.(CVE-2015-8961i1/4%0
- Buffer overflow in the oz_cdev_write function in drivers/staging/ozwpan/ozcdev.c in the Linux kernel before 3.12 allows local users to cause a denial of service or possibly have unspecified other impact via a crafted write operation.(CVE-2013-4513i1/4%0
- The nfnetlink_rcv_batch() function in 'net/netfilter/nfnetlink.c' in the Linux kernel before 4.5 does not check whether a batch message's length field is large enough, which allows local users to obtain sensitive information from kernel memory or cause a denial of service (infinite loop or out-of-bounds read) by leveraging the CAP_NET_ADMIN capability.(CVE-2016-7917i1/4%0
- Array index error in the kvm_vm_ioctl_create_vcpu function in virt/kvm/kvm_main.c in the KVM subsystem in the Linux kernel through 3.12.5 allows local users to gain privileges via a large id value.(CVE-2013-4587i1/4%0
- A leak of information was possible when issuing a netlink command of the stack memory area leading up to this function call. An attacker could use this to determine stack information for use in a later exploit.(CVE-2016-5243i1/4%0
- An issue was discovered in the Linux kernel in the F2FS filesystem code. A NULL pointer dereference in fscrypt_do_page_crypto() in the fs/crypto/crypto.c function can occur when operating on a file on a corrupted f2fs image.(CVE-2018-14616i1/4%0
- An out-of-bounds flaw was found in the kernel, where the sco_sock_bind() function (bluetooth/sco) did not check the length of its sockaddr parameter. As a result, more kernel memory was copied out than required, leaking information from the kernel stack (including kernel addresses). A local user could exploit this flaw to bypass kernel ASLR or leak other information.(CVE-2015-8575i1/4%0
- A denial of service vulnerability was found in the WhiteHEAT USB Serial Driver (whiteheat_attach function in drivers/usb/serial/whiteheat.c). In the driver, the COMMAND_PORT variable was hard coded and set to 4 (5th element). The driver assumed that the number of ports would always be 5 and used port number 5 as the command port. However, when using a USB device in which the number of ports was set to a number less than 5 (for example, 3), the driver triggered a kernel NULL-pointer dereference. A non-privileged attacker could use this flaw to panic the host.(CVE-2015-5257i1/4%0
- The LLC subsystem in the Linux kernel does not ensure that a certain destructor exists in required circumstances, which allows local users to cause a denial of service (BUG_ON) or possibly have unspecified other impact via crafted system calls.(CVE-2017-6345i1/4%0
- A vulnerability was found in Linux kernel. There is an information leak in file sound/core/timer.c of the latest mainline Linux kernel. The stack object aEURoer1aEUR has a total size of 32 bytes. Its field aEURoeeventaEUR and aEURoevalaEUR both contain 4 bytes padding. These 8 bytes padding bytes are sent to user without being initialized.(CVE-2016-4578i1/4%0
- An information leak flaw was found in the way the Linux kernel changed certain segment registers and thread-local storage (TLS) during a context switch. A local, unprivileged user could use this flaw to leak the user space TLS base address of an arbitrary process.(CVE-2014-9419i1/4%0
- A flaw was found in the way memory was being allocated on the stack for user space binaries. If heap (or different memory region) and stack memory regions were adjacent to each other, an attacker could use this flaw to jump over the stack guard gap, cause controlled memory corruption on process stack or the adjacent memory region, and thus increase their privileges on the system. This is a kernel-side mitigation which increases the stack guard gap size from one page to 1 MiB to make successful exploitation of this issue more difficult.(CVE-2017-1000364i1/4%0
- A flaw was found in the Linux kernel's handling of clearing SELinux attributes on /proc/pid/attr files. An empty (null) write to this file can crash the system by causing the system to attempt to access unmapped kernel memory.(CVE-2017-2618i1/4%0
- A use-after-free vulnerability was found in ALSA pcm layer, which allows local users to cause a denial of service, memory corruption, or possibly other unspecified impact. Due to the nature of the flaw, privilege escalation cannot be fully ruled out, although we believe it is unlikely.(CVE-2016-9794i1/4%0
- A flaw was found in the way the Linux kernel's floppy driver handled user space provided data in certain error code paths while processing FDRAWCMD IOCTL commands. A local user with write access to /dev/fdX could use this flaw to free (using the kfree() function) arbitrary kernel memory. (CVE-2014-1737, Important)t was found that the Linux kernel's floppy driver leaked internal kernel memory addresses to user space during the processing of the FDRAWCMD IOCTL command. A local user with write access to /dev/fdX could use this flaw to obtain information about the kernel heap arrangement. (CVE-2014-1738, Low)Note: A local user with write access to /dev/fdX could use these two flaws (CVE-2014-1737 in combination with CVE-2014-1738) to escalate their privileges on the system.(CVE-2014-1737i1/4%0
- An out-of-bounds memory access flaw was found in the Linux kernel's aiptek USB tablet driver (aiptek_probe() function in drivers/input/tablet/aiptek.c). The driver assumed that the interface always had at least one endpoint. By using a specially crafted USB device with no endpoints on one of its interfaces, an unprivileged user with physical access to the system could trigger a kernel NULL pointer dereference, causing the system to panic.(CVE-2015-7515i1/4%0
