EulerOS Virtualization 3.0.1.0 : kernel (EulerOS-SA-2019-1480)

High Nessus Plugin ID 124804

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 flaw was found in the way the Linux kernel's futex subsystem handled the requeuing of certain Priority Inheritance (PI) futexes. A local, unprivileged user could use this flaw to escalate their privileges on the system.(CVE-2014-3153)

- An out-of-bounds write flaw was found in the way the Apple Magic Mouse/Trackpad multi-touch driver handled Human Interface Device (HID) reports with an invalid size. An attacker with physical access to the system could use this flaw to crash the system or, potentially, escalate their privileges on the system.(CVE-2014-3181)

- An out-of-bounds read flaw was found in the way the Logitech Unifying receiver driver handled HID reports with an invalid device_index value. An attacker with physical access to the system could use this flaw to crash the system or, potentially, escalate their privileges on the system.(CVE-2014-3182)

- Multiple out-of-bounds write flaws were found in the way the Cherry Cymotion keyboard driver, KYE/Genius device drivers, Logitech device drivers, Monterey Genius KB29E keyboard driver, Petalynx Maxter remote control driver, and Sunplus wireless desktop driver handled HID reports with an invalid report descriptor size. An attacker with physical access to the system could use either of these flaws to write data past an allocated memory buffer.(CVE-2014-3184)

- A memory corruption flaw was found in the way the USB ConnectTech WhiteHEAT serial driver processed completion commands sent via USB Request Blocks buffers. An attacker with physical access to the system could use this flaw to crash the system or, potentially, escalate their privileges on the system.(CVE-2014-3185)

- It was found that Linux kernel's ptrace subsystem did not properly sanitize the address-space-control bits when the program-status word (PSW) was being set. On IBM S/390 systems, a local, unprivileged user could use this flaw to set address-space-control bits to the kernel space, and thus gain read and write access to kernel memory.(CVE-2014-3534)

- A flaw was found in the way the Linux kernel's kvm_iommu_map_pages() function handled IOMMU mapping failures. A privileged user in a guest with an assigned host device could use this flaw to crash the host.(CVE-2014-3601)

- It was found that KVM's Write to Model Specific Register (WRMSR) instruction emulation would write non-canonical values passed in by the guest to certain MSRs in the host's context. A privileged guest user could use this flaw to crash the host.(CVE-2014-3610)

- A race condition flaw was found in the way the Linux kernel's KVM subsystem handled PIT (Programmable Interval Timer) emulation. A guest user who has access to the PIT I/O ports could use this flaw to crash the host.(CVE-2014-3611)

- 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-2014-3631)

- It was found that the Linux kernel's KVM subsystem did not handle the VM exits gracefully for the invept (Invalidate Translations Derived from EPT) instructions. On hosts with an Intel processor and invept VM exit support, an unprivileged guest user could use these instructions to crash the guest.(CVE-2014-3645)

- It was found that the Linux kernel's KVM subsystem did not handle the VM exits gracefully for the invvpid (Invalidate Translations Based on VPID) instructions.
On hosts with an Intel processor and invppid VM exit support, an unprivileged guest user could use these instructions to crash the guest.(CVE-2014-3646)

- A flaw was found in the way the Linux kernel's KVM subsystem handled non-canonical addresses when emulating instructions that change the RIP (for example, branches or calls). A guest user with access to an I/O or MMIO region could use this flaw to crash the guest.(CVE-2014-3647)

- A flaw was found in the way the Linux kernel's Stream Control Transmission Protocol (SCTP) implementation handled malformed Address Configuration Change Chunks (ASCONF). A remote attacker could use either of these flaws to crash the system.(CVE-2014-3673)

- A flaw was found in the way the Linux kernel's Stream Control Transmission Protocol (SCTP) implementation handled duplicate Address Configuration Change Chunks (ASCONF). A remote attacker could use either of these flaws to crash the system.(CVE-2014-3687)

- A flaw was found in the way the Linux kernel's Stream Control Transmission Protocol (SCTP) implementation handled the association's output queue. A remote attacker could send specially crafted packets that would cause the system to use an excessive amount of memory, leading to a denial of service.(CVE-2014-3688)

- It was found that the Linux kernel's KVM implementation did not ensure that the host CR4 control register value remained unchanged across VM entries on the same virtual CPU. A local, unprivileged user could use this flaw to cause a denial of service on the system.(CVE-2014-3690)

- An out-of-bounds memory access flaw was found in the Linux kernel's system call auditing implementation. On a system with existing audit rules defined, a local, unprivileged user could use this flaw to leak kernel memory to user space or, potentially, crash the system.(CVE-2014-3917)

- A flaw was found in the way Linux kernel's Transparent Huge Pages (THP) implementation handled non-huge page migration. A local, unprivileged user could use this flaw to crash the kernel by migrating transparent hugepages.(CVE-2014-3940)

- The capabilities implementation in the Linux kernel before 3.14.8 does not properly consider that namespaces are inapplicable to inodes, which allows local users to bypass intended chmod restrictions by first creating a user namespace, as demonstrated by setting the setgid bit on a file with group ownership of root.(CVE-2014-4014)

- An information leak flaw was found in the RAM Disks Memory Copy (rd_mcp) backend driver of the iSCSI Target subsystem of the Linux kernel. A privileged user could use this flaw to leak the contents of kernel memory to an iSCSI initiator remote client.(CVE-2014-4027)

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
