CVE-2018-1000001

Priority
High
Description
[Libc Realpath Buffer Underflow]
Ubuntu-Description
libc does not account for all the possible return values from the
kernel getcwd(2) syscall; arbitrary code execution may result from
applications making further assumptions on the return value from the
getcwd(3) libary function.

Notes
 sarnold> I wonder where Go, busybox, and similar "do it ourselves" tools fit.
  I added dietlibc and musl to this page out of an abundance of caution. Someone
  should investigate.
