Description Murray McAllister 2014-12-08 06:52:46 UTC

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:
