There is a heap-based buffer overflow in string_vformat (string.c). The currently known exploit uses a extraordinary long EHLO string to crash the Exim process that is receiving the message. While at this mode of operation Exim already dropped its privileges, other paths to reach the vulnerable code may exist.
An integer overflow in WhatsApp media parsing libraries allows a remote attacker to perform an out-of-bounds write on the heap via specially-crafted EXIF tags in WEBP images.
VMware ESXi, Workstation and Fusion contain out-of-bounds read/write vulnerabilities in the pixel shader functionality. Exploitation of these issues require an attacker to have access to a virtual machine with 3D graphics enabled. It is not enabled by default on ESXi and is enabled by default on Workstation and Fusion. Successful exploitation of the out-of-bounds read issue (CVE-2019-5521) may lead to information disclosure or may allow attackers with normal user privileges to create a denial-of-service condition on the host. The out-of-bounds write issue (CVE-2019-5684) can be exploited only if the host has an affected NVIDIA graphics driver. Successful exploitation of this issue may lead to code execution on the host.
The vulnerability is limited to the DUP framework during the time window when a DUP is being executed by an administrator. During this time window, a locally authenticated low privilege malicious user potentially could exploit this vulnerability by tricking an administrator into running a trusted binary, causing it to load a malicious DLL and allowing the attacker to execute arbitrary code on the victim system. The vulnerability does not affect the actual binary payload that the DUP delivers.
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.
vBulletin 5.x through 5.5.4 allows remote command execution via the widgetConfig[code] parameter in an ajax/render/widget_php routestring request.
In radare2 before 3.9.0, a command injection vulnerability exists in bin_symbols() in libr/core/cbin.c. By using a crafted executable file, it's possible to execute arbitrary shell commands with the permissions of the victim. This vulnerability is due to an insufficient fix for CVE-2019-14745 and improper handling of symbol names embedded in executables.
In radare2 before 3.7.0, a command injection vulnerability exists in bin_symbols() in libr/core/cbin.c. By using a crafted executable file, it's possible to execute arbitrary shell commands with the permissions of the victim. This vulnerability is due to improper handling of symbol names embedded in executables.
