FreeBSD -- select(2) file descriptor set overflow causes stack overflow

Problem Description: libcasper3 communicates with helper processes via UNIX domain sockets, and uses the select2 system call to wait for data to become available. However, it does not verify that its socket descriptor fits within select2's descriptor set size limit of FDSETSIZE 1024. Impact: An...

FreeBSD -- Heap overflow in FUSE_LISTXATTR

FreeBSD -- Kernel use-after-free via file descriptor syscalls

Problem Description: A file descriptor can be closed while a thread is blocked in a poll2 or select2 call waiting for that descriptor. Because the blocked thread does not hold a reference to the underlying object, this closure may result in the object being freed while the thread remains blocked...
