Red Hat Security Advisory 2020-1980-01 - Git is a distributed revision control system with a decentralized architecture. As opposed to centralized version control systems with a client-server model, Git ensures that each working copy of a Git repository is an exact copy with complete revision history. This not only allows the user to work on and contribute to projects without the need to have permission to push the changes to their official repositories, but also makes it possible for the user to work with no network connection. Issues addressed include a password leak vulnerability.

Red Hat Security Advisory 2020-1422-01 - This release of Red Hat build of Eclipse Vert.x 3.9.0 includes security updates, bug fixes, and enhancements. For more information, see the release notes page listed in the References section.

The HC.Server service in Hosting Controller HC10 10.14 allows an Invalid Pointer Write DoS if attackers can reach the service on port 8794. In addition this can potentially be leveraged for post exploit persistence with SYSTEM privileges, if physical access or malware is involved. If a physical attacker or malware can set its own program for the service failure recovery options, it can be used to maintain persistence. Afterwards, it can be triggered by sending a malicious request to DoS the service, which in turn can start the attackers recovery program. The attackers program can then try restarting the affected service to try an stay unnoticed by calling "sc start HCServerService". Services failure flag recovery options for "enabling actions for stops or errors" and can be set in the services "Recovery" properties tab or on the command line. Authentication is not required to reach the vulnerable service, this was tested successfully on Windows 7/10.

Microsoft Windows 7 Build 7601 (x86) local privilege escalation exploit.

Apple Security Advisory 2019-10-07-4 - iCloud for Windows 7.14 is now available and addresses buffer overflow, code execution, and cross site scripting vulnerabilities.

The Plantronics Hub client application for Windows makes use of an automatic update service SpokesUpdateService.exe which automatically executes a file specified in the MajorUpgrade.config configuration file as SYSTEM. The configuration file is writable by all users by default. This module has been tested successfully on Plantronics Hub version 3.13.2 on Windows 7 SP1 (x64). This Metasploit module has been tested successfully on Plantronics Hub version 3.13.2 on Windows 7 SP1 (x64).

The Windscribe VPN client application for Windows makes use of a Windows service WindscribeService.exe which exposes a named pipe \.pipeWindscribeService allowing execution of programs with elevated privileges. Windscribe versions prior to 1.82 do not validate user-supplied program names, allowing execution of arbitrary commands as SYSTEM. This Metasploit module has been tested successfully on Windscribe versions 1.80 and 1.81 on Windows 7 SP1 (x64).

AVideo Platform version 8.1 suffers from a cross site request forgery vulnerability.

Red Hat Security Advisory 2020-1050-01 - The Common UNIX Printing System provides a portable printing layer for Linux, UNIX, and similar operating systems. Issues addressed include a cross site request forgery vulnerability.

This Metasploit module leverages a trusted file overwrite with a dll hijacking vulnerability to gain SYSTEM-level access on vulnerable Windows 10 x64 targets.

This Metasploit module exploits a NULL pointer dereference vulnerability in MNGetpItemFromIndex(), which is reachable via a NtUserMNDragOver() system call. The NULL pointer dereference occurs because the xxxMNFindWindowFromPoint() function does not effectively check the validity of the tagPOPUPMENU objects it processes before passing them on to MNGetpItemFromIndex(), where the NULL pointer dereference will occur. This module has been tested against Windows 7 x86 SP0 and SP1. Offsets within the solution may need to be adjusted to work with other versions of Windows, such as Windows Server 2008.

Gentoo Linux Security Advisory 202003-38 - A vulnerability in Imagick PHP extension might allow an attacker to execute arbitrary code. Versions less than 3.4.4 are affected.

Red Hat Security Advisory 2020-1112-01 - PHP is an HTML-embedded scripting language commonly used with the Apache HTTP Server. Issues addressed include a cross site scripting vulnerability.

FreeBSD Security Advisory - While processing acknowledgements, the RACK code uses several linked lists to maintain state entries. A malicious attacker can cause the lists to grow unbounded. This can cause an expensive list traversal on every packet being processed, leading to resource exhaustion and a denial of service. An attacker with the ability to send specially crafted TCP traffic to a victim system can degrade network performance and/or consume excessive CPU by exploiting the inefficiency of traversing the potentially very large RACK linked lists with relatively small bandwidth cost.

FreeBSD Security Advisory - With certain inputs, iconv may write beyond the end of the output buffer. Depending on the way in which iconv is used, an attacker may be able to create a denial of service, provoke incorrect program behavior, or induce a remote code execution. iconv is a libc library function and the nature of possible attacks will depend on the way in which iconv is used by applications or daemons.

FreeBSD Security Advisory - To implement one particular ioctl, the Linux emulation code used a special interface present in the cd(4) driver which allows it to copy subchannel information directly to a kernel address. This interface was erroneously made accessible to userland, allowing users with read access to a cd(4) device to arbitrarily overwrite kernel memory when some media is present in the device. A user in the operator group can make use of this interface to gain root privileges on a system with a cd(4) device when some media is present in the device.

FreeBSD Security Advisory - A bug causes up to three bytes of kernel stack memory to be written to disk as uninitialized directory entry padding. This data can be viewed by any user with read access to the directory. Additionally, a malicious user with write access to a directory can cause up to 254 bytes of kernel stack memory to be exposed. Some amount of the kernel stack is disclosed and written out to the filesystem.

FreeBSD Security Advisory - Insufficient validation of environment variables in the telnet client supplied in FreeBSD can lead to stack-based buffer overflows. A stack-based overflow is present in the handling of environment variables when connecting via the telnet client to remote telnet servers. This issue only affects the telnet client. Inbound telnet sessions to telnetd(8) are not affected by this issue. These buffer overflows may be triggered when connecting to a malicious server, or by an active attacker in the network path between the client and server. Specially crafted TELNET command sequences may cause the execution of arbitrary code with the privileges of the user invoking telnet(1).

FreeBSD Security Advisory - Due to insufficient initialization of memory copied to userland in the components listed above small amounts of kernel memory may be disclosed to userland processes. A user who can invoke 32-bit FreeBSD ioctls may be able to read the contents of small portions of kernel memory. Such memory might contain sensitive information, such as portions of the file cache or terminal buffers. This information might be directly useful, or it might be leveraged to obtain elevated privileges in some way; for example, a terminal buffer might include a user-entered password.

FreeBSD Security Advisory - System calls operating on file descriptors obtain a reference to relevant struct file which due to a programming error was not always put back, which in turn could be used to overflow the counter of affected struct file. A local user can use this flaw to obtain access to files, directories, sockets etc. opened by processes owned by other users. If obtained struct file represents a directory from outside of user's jail, it can be used to access files outside of the jail. If the user in question is a jailed root they can obtain root privileges on the host system.

FreeBSD Security Advisory - The pci_xhci_device_doorbell() function does not validate the 'epid' and 'streamid' provided by the guest, leading to an out-of-bounds read. A misbehaving bhyve guest could crash the system or access memory that it should not be able to.

FreeBSD Security Advisory - If a process attempts to transmit rights over a UNIX-domain socket and an error causes the attempt to fail, references acquired on the rights are not released and are leaked. This bug can be used to cause the reference counter to wrap around and free the corresponding file structure. A local user can exploit the bug to gain root privileges or escape from a jail.

FreeBSD Security Advisory - The decompressor used in bzip2 contains a bug which can lead to an out-of-bounds write when processing a specially crafted bzip2(1) file. bzip2recover contains a heap use-after-free bug which can be triggered when processing a specially crafted bzip2(1) file. An attacker who can cause maliciously crafted input to be processed may trigger either of these bugs. The bzip2recover bug may cause a crash, permitting a denial-of-service. The bzip2 decompressor bug could potentially be exploited to execute arbitrary code. Note that some utilities, including the tar(1) archiver and the bspatch(1) binary patching utility (used in portsnap(8) and freebsd-update(8)) decompress bzip2(1)-compressed data internally; system administrators should assume that their systems will at some point decompress bzip2(1)-compressed data even if they never explicitly invoke the bunzip2(1) utility.

FreeBSD Security Advisory - The ICMPv6 input path incorrectly handles cases where an MLDv2 listener query packet is internally fragmented across multiple mbufs. A remote attacker may be able to cause an out-of-bounds read or write that may cause the kernel to attempt to access an unmapped page and subsequently panic.

FreeBSD Security Advisory - A function extracting the length from type-length-value encoding is not properly validating the submitted length. A remote user could cause, for example, an out-of-bounds read, decoding of unrelated data, or trigger a crash of the software such as bsnmpd resulting in a denial of service.

FreeBSD Security Advisory - The e1000 network adapters permit a variety of modifications to an Ethernet packet when it is being transmitted. These include the insertion of IP and TCP checksums, insertion of an Ethernet VLAN header, and TCP segmentation offload ("TSO"). The e1000 device model uses an on-stack buffer to generate the modified packet header when simulating these modifications on transmitted packets. When TCP segmentation offload is requested for a transmitted packet, the e1000 device model used a guest-provided value to determine the size of the on-stack buffer without validation. The subsequent header generation could overflow an incorrectly sized buffer or indirect a pointer composed of stack garbage. A misbehaving bhyve guest could overwrite memory in the bhyve process on the host.
