Memprocfs
Monthly
DLL and shared-library hijacking in ufrisk MemProcFS versions prior to 5.17 enables local arbitrary code execution through six distinct attack surfaces. Unsafe library-loading patterns-including unqualified LoadLibraryU and dlopen calls for vmmpyc, libMSCompression, and plugin DLLs-allow attackers to plant malicious libraries in the working directory or manipulate LD_LIBRARY_PATH. Exploitation requires user interaction (CVSS UI:P) but no authentication (PR:N), achieving high confidentiality, integrity, and availability impact. No public exploit identified at time of analysis.
