Windows Kernel Information Disclosure Vulnerability

The HPE-provided Windows firmware installer for certain Gen9, Gen8, G7,and G6 HPE servers allows local disclosure of privileged information. This issue was resolved in previously provided firmware updates as follows. The HPE Windows firmware installer was updated in the system ROM updates which also addressed the original Spectre/Meltdown set of vulnerabilities. At that time, the Windows firmware installer was also updated in the versions of HPE Integrated Lights-Out 2, 3, and 4 (iLO 2, 3, and 4) listed in the security bulletin. The updated HPE Windows firmware installer was released in the system ROM and HPE Integrated Lights-Out (iLO) releases documented in earlier HPE Security Bulletins: HPESBHF03805, HPESBHF03835, HPESBHF03831. Windows-based systems that have already been updated to the system ROM or iLO versions described in these security bulletins require no further action.

An issue was discovered in BlueStacks 4.110 and below on macOS and on 4.120 and below on Windows. BlueStacks employs Android running in a virtual machine (VM) to enable Android apps to run on Windows or MacOS. Bug is in a local arbitrary file read through a system service call. The impacted method runs with System admin privilege and if given the file name as parameter returns you the content of file. A malicious app using the affected method can then read the content of any system file which it is not authorized to read

An issue was discovered in the proc_pid_stack function in fs/proc/base.c in the Linux kernel through 4.18.11. It does not ensure that only root may inspect the kernel stack of an arbitrary task, allowing a local attacker to exploit racy stack unwinding and leak kernel task stack contents.

The vmw_gb_surface_define_ioctl function (accessible via DRM_IOCTL_VMW_GB_SURFACE_CREATE) in drivers/gpu/drm/vmwgfx/vmwgfx_surface.c in the Linux kernel through 4.11.4 defines a backup_handle variable but does not give it an initial value. If one attempts to create a GB surface, with a previously allocated DMA buffer to be used as a backup buffer, the backup_handle variable does not get written to and is then later returned to user space, allowing local users to obtain sensitive information from uninitialized kernel memory via a crafted ioctl call.

nfsd in the Linux kernel through 4.6.3 allows local users to bypass intended file-permission restrictions by setting a POSIX ACL, related to nfs2acl.c, nfs3acl.c, and nfs4acl.c.

In the Linux kernel before 4.1.4, a buffer overflow occurs when checking userspace params in drivers/media/dvb-frontends/cx24116.c. The maximum size for a DiSEqC command is 6, according to the userspace API. However, the code allows larger values such as 23.

Windows Clustered Shared Volume Information Disclosure Vulnerability

Windows Failover Cluster Information Disclosure Vulnerability

MagniComp SysInfo before 10-H81, as shipped with BMC BladeLogic Automation and other products, contains an information exposure vulnerability in which a local unprivileged user is able to read any root (uid 0) owned file on the system, regardless of the file permissions. Confidential information such as password hashes (/etc/shadow) or other secrets (such as log files or private keys) can be leaked to the attacker. The vulnerability has a confidentiality impact, but has no direct impact on system integrity or availability.

In the Linux kernel through 4.15.4, the floppy driver reveals the addresses of kernel functions and global variables using printk calls within the function show_floppy in drivers/block/floppy.c. An attacker can read this information from dmesg and use the addresses to find the locations of kernel code and data and bypass kernel security protections such as KASLR.

Windows NTFS Information Disclosure Vulnerability

A certain Debian patch to the IPv6 implementation in the Linux kernel 3.2.x through 3.2.63 does not properly validate arguments in ipv6_select_ident function calls, which allows local users to cause a denial of service (NULL pointer dereference and system crash) by leveraging (1) tun or (2) macvtap device access.
