Description Murray McAllister 2014-12-08 01:52:46 EST

Thomas Jarosch of Intra2net AG reported a number of denial of service issues (resource consumption) in the ELF parser used by file(1). Using file(1) on a specially-crafted ELF binary could lead to a denial of service (resource consumption).

Upstream fixes:

https://github.com/file/file/commit/b4c01141e5367f247b84dcaf6aefbb4e741842b8
https://github.com/file/file/commit/d7cdad007c507e6c79f51f058dd77fab70ceb9f6

Due to some regressions found when testing, the following commits are also required:
