Published: 18 October 2017
scanf and related functions in glibc before 2.15 allow local users to cause a denial of service (segmentation fault) via a large string of 0s.
Notes
| Author | Note |
|---|---|
| seth-arnold | other long strings also crash scanf but only 0 is representable, the standard is slightly lenient here. Second patch may not be strictly necessary, see the discussion at the bug report for opinions. |
