FreeBSD -- Heap overflow in FUSE_LISTXATTR

Problem Description: When a fusefs file system implements extended attributes, the kernel may send a FUSELISTXATTR message to the userspace daemon to retrieve the list of extended attributes for a given file. The FUSE protocol requires the daemon to return a packed list of NUL-terminated strings...

FreeBSD Security Advisory - FreeBSD-SA-26:18.setcred

FreeBSD Security Advisory - The setcred2 system call is only available to privileged users. However, before the privilege level of the caller is checked, the user-supplied list of supplementary groups is copied into a fixed-size kernel stack buffer without first validating its length. If the...

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 -- Missing validation in ptrace(PT_SC_REMOTE)

Problem Description: ptracePTSCREMOTE failed to properly validate parameters for the syscall2 and syscall2 meta-system calls. As a result, a user with the ability to debug a process may trigger arbitrary code execution in the kernel, even if the target process has no special privileges. Impact: T...

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...

FreeBSD -- Incorrect libcap_net limitation list manipulation

Problem Description: In the case of the capnet service, when a key present in the old limit was omitted from the new limit, the missing key was treated as "allow any" instead of being rejected. Impact: In certain scenarios, an application that had previously restricted a subset of network...
