057c7f8520ab2ed56e7d9e82678764871158a2cd733dc5a66c8955746dc99b8fREvil ransomware looks for and executes DLLs in its current directory. Therefore, we can hijack a DLL, execute our own code, and control and terminate the malware pre-encryption. The exploit DLL checks if the current directory is "C:\Windows\System32" and if not we grab our process ID and terminate. We do not need to rely on hash signatures or third-party products as the malware's flaw does the work for us. Endpoint protection systems and or antivirus can potentially be killed prior to executing malware, but this method cannot as there's nothing to kill the DLL that just lives on disk waiting. From a defensive perspective you can add the DLLs to a specific network share containing important data as a layered approach. All basic tests were conducted successfully in a virtual machine environment.

4c448e0e5a0914fcc57d5d435b52042feff16ca95bf5c04fea342caeb1515eacThis Metasploit module exploits an authentication bypass vulnerability in the F5 BIG-IP iControl REST service to gain access to the admin account, which is capable of executing commands through the /mgmt/tm/util/bash endpoint. Successful exploitation results in remote code execution as the root user.

A local attacker could possibly use this to expose sensitive information. It was discovered that the MMC/SD subsystem in the Linux kernel did not properly handle read errors from SD cards in certain situations. An attacker could possibly use this to expose sensitive information.

A local attacker could possibly use this to expose sensitive information. Demi Marie Obenour and Simon Gaiser discovered that several Xen para- virtualization device frontends did not properly restrict the access rights of device backends. An attacker could possibly use a malicious Xen backend to gain access to memory pages of a guest VM or cause a denial of service in the guest.

691a35428f308c736b0b1c54fe6cb68b24805afc0173f36b49281af792f6943aAppleVideoDecoder suffers from an out-of-bounds free vulnerability. The attached video file contains a malformed HEVC Decoder Configuration Record that leads to an out-of-bounds free in CreateHeaderBuffer. When copying the VPS, PPS and SPS, the destination pointer is incremented, and if the copied data is larger than the length specified in the input file, it breaks and falls through to a condition that frees the destination pointer, even though it has been incremented. This could free the chunk allocated next to the destination memory.

A privileged or physically proximate attacker could use this to cause a denial of service. It was discovered that a race condition existed in the network scheduling subsystem of the Linux kernel, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service or possibly execute arbitrary code.
