Categoría:	FreeBSD Local Security Checks
Título:	FreeBSD Security Advisory (FreeBSD-SA-03:17.procfs.asc)
Resumen:	NOSUMMARY
Descripción:	Description: The remote host is missing an update to the system as announced in the referenced advisory FreeBSD-SA-03:17.procfs.asc The process file system, procfs(5), implements a view of the system process table inside the file system. It is normally mounted on /proc, and is required for 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. 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 region of kernel memory to be returned to the user. Solution: Upgrade your system to the appropriate stable release or security branch dated after the correction date http://www.securityspace.com/smysecure/catid.html?in=FreeBSD-SA-03:17.procfs.asc
