kernel: kvm: noncanonical rip after emulation

arch/x86/kvm/emulate.c in the KVM subsystem in the Linux kernel through 3.17.2 does not properly perform RIP changes, which allows guest OS users to cause a denial of service (guest OS crash) via a crafted application.

kernel: kvm: vmx: invvpid vm exit not handled

arch/x86/kvm/vmx.c in the KVM subsystem in the Linux kernel through 3.17.2 does not have an exit handler for the INVVPID instruction, which allows guest OS users to cause a denial of service (guest OS crash) via a crafted application.

kernel: kvm: vmx: invept vm exit not handled

arch/x86/kvm/vmx.c in the KVM subsystem in the Linux kernel before 3.12 does not have an exit handler for the INVEPT instruction, which allows guest OS users to cause a denial of service (guest OS crash) via a crafted application.

OpenJDK: certificate options parsing uncaught exception (JSSE, 8068720)

Unspecified vulnerability in Oracle Java SE 5.0u81, 6u91, 7u76, and 8u40, and JRockit R28.3.5, allows remote attackers to affect availability via vectors related to JSSE.

Qemu: usb: ehci: memory leakage in ehci_init_transfer

Quick Emulator (Qemu) built with the USB EHCI Emulation support is vulnerable to a memory leakage issue. It could occur while processing packet data in 'ehci_init_transfer'. A guest user/process could use this issue to leak host memory, resulting in DoS for a host.

Qemu: 9pfs: memory leakage via proxy/handle callbacks

Memory leak in hw/9pfs/9p.c in QEMU (aka Quick Emulator) allows local privileged guest OS users to cause a denial of service (host memory consumption and possibly QEMU process crash) by leveraging a missing cleanup operation in FileOperations.

Qemu: display: virtio-gpu: memory leakage when destroying gpu resource

Quick Emulator (Qemu) built with the Virtio GPU Device emulator support is vulnerable to a memory leakage issue. It could occur while destroying gpu resource object in 'virtio_gpu_resource_destroy'. A guest user/process could use this flaw to leak host memory bytes, resulting in DoS for a host.

Qemu: 9pfs: memory leakage via proxy/handle callbacks

Memory leak in hw/9pfs/9p-handle.c in QEMU (aka Quick Emulator) allows local privileged guest OS users to cause a denial of service (host memory consumption and possibly QEMU process crash) by leveraging a missing cleanup operation in the handle backend.

Qemu: 9pfs: memory leakage via proxy/handle callbacks

Memory leak in hw/9pfs/9p-proxy.c in QEMU (aka Quick Emulator) allows local privileged guest OS users to cause a denial of service (host memory consumption and possibly QEMU process crash) by leveraging a missing cleanup operation in the proxy backend.

Qemu: 9pfs: memory leakage via proxy/handle callbacks

Memory leak in the v9fs_device_unrealize_common function in hw/9pfs/9p.c in QEMU (aka Quick Emulator) allows local privileged guest OS users to cause a denial of service (host memory consumption and possibly QEMU process crash) via vectors involving the order of resource cleanup.

Qemu: display: virtio-gpu: memory leakage while updating cursor data

QEMU (aka Quick Emulator) built with the Virtio GPU Device emulator support is vulnerable to a memory leakage issue. It could occur while updating the cursor data in update_cursor_data_virgl. A guest user/process could use this flaw to leak host memory bytes, resulting in DoS for a host.

Qemu: usb: redirector: memory leakage when destroying redirector

Quick Emulator (Qemu) built with the USB redirector usb-guest support is vulnerable to a memory leakage flaw. It could occur while destroying the USB redirector in 'usbredir_handle_destroy'. A guest user/process could use this issue to leak host memory, resulting in DoS for a host.

openstack-neutron: L2 agent DoS through incorrect allowed address pairs

OpenStack Neutron before 2014.2.4 (juno) and 2015.1.x before 2015.1.1 (kilo), when using the IPTables firewall driver, allows remote authenticated users to cause a denial of service (L2 agent crash) by adding an address pair that is rejected by the ipset tool.

In wlan AP driver, there is a possible information disclosure due to an uncaught exception. This could lead to remote (proximal/adjacent) information disclosure with no additional execution privileges needed. User interaction is not needed for exploitation. Patch ID: WCNCR00408868; Issue ID: MSV-3031.

DedeCMS update_guide.php path traversal

A vulnerability has been found in DedeCMS 5.7.112-UTF8 and classified as problematic. Affected by this vulnerability is an unknown functionality of the file update_guide.php. The manipulation of the argument files leads to path traversal: '../filedir'. The attack can be launched remotely. The exploit has been disclosed to the public and may be used. The identifier VDB-260473 was assigned to this vulnerability. NOTE: The vendor was contacted early about this disclosure but did not respond in any way.

Triggered crash on direct RRDP access

NLnet Labs Krill supports direct access to the RRDP repository content through its built-in web server at the "/rrdp" endpoint. Prior to 0.12.1 a direct query for any existing directory under "/rrdp/", rather than an RRDP file such as "/rrdp/notification.xml" as would be expected, causes Krill to crash. If the built-in "/rrdp" endpoint is exposed directly to the internet, then malicious remote parties can cause the publication server to crash. The repository content is not affected by this, but the availability of the server and repository can cause issues if this attack is persistent and is not mitigated.

DedeCMS path traversal

A vulnerability classified as problematic has been found in DedeCMS 5.7.114. This affects an unknown part of the file /sys_verifies.php?action=view. The manipulation of the argument filename with the input ../../../../../etc/passwd leads to path traversal: '../filedir'. It is possible to initiate the attack remotely. The exploit has been disclosed to the public and may be used. The identifier VDB-263889 was assigned to this vulnerability. NOTE: The vendor was contacted early about this disclosure but did not respond in any way.

A directory traversal issue was discovered in OpenSlides before 4.2.5. Files can be uploaded to OpenSlides meetings and organized in folders. The interface allows users to download a ZIP archive that contains all files in a folder and its subfolders. If an attacker specifies the title of a file or folder as a relative or absolute path (e.g., ../../../etc/passwd), the ZIP archive generated for download converts that title into a path. Depending on the extraction tool used by the user, this might overwrite files locally outside of the chosen directory.

Ivanti Docs@Work for Android, before 2.26.0 is affected by the 'Dirty Stream' vulnerability. The application fails to properly sanitize file names, resulting in a path traversal-affiliated vulnerability. This potentially enables other malicious apps on the device to read sensitive information stored in the app root.
