RedLine.Stealer MVID-2022-0578 Code Execution
Posted May 3, 2022
Authored by malvuln | Site malvuln.com

RedLine looks for and loads a DLL named "wow64log.dll" in Windows\System32. Therefore, we can drop our own DLL to intercept and terminate the malware. The exploit DLL will simply display a Win32API message box and call exit(). Our RedLine exploit DLL must export the "InterlockedExchange" function or it fails with an error. We do not need to rely on a hash signature or third-party product, the malware vulnerability will do 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.

OpenSSL Toolkit 3.0.3
Posted May 3, 2022
Site openssl.org

OpenSSL is a robust, fully featured Open Source toolkit implementing the Secure Sockets Layer (SSL v2/v3) and Transport Layer Security (TLS v1) protocols with full-strength cryptography world-wide. The 3.x series is the current major version of OpenSSL.

Changes: Fixed a bug in the c_rehash script which was not properly sanitizing shell metacharacters to prevent command injection. Fixed a bug in the function OCSP_basic_verify that verifies the signer certificate on an OCSP response. Fixed a bug where the RC4-MD5 ciphersuite incorrectly used the AAD data as the MAC key. Fixed a bug in the OPENSSL_LH_flush() function that breaks reuse of the memory occupied by the removed hash table entries.
