...or the complete operation of programs such as ps(1) and w(1). The Linux process file system, linprocfs(5), emulates a subset of Linux's process file system and is required for the complete operation of some Linux binaries. II. Problem Description The procfs and linprocfs implementations use uiomove(9) and the related `struct uio' in order to fulfill read and write requests. Several cases were identified where members of `struct uio' were not properly validated before being used. In particular, the `uio_offset' member may be negative or extremely large, and was used to compute the...
