Description Vasyl Kaigorodov 2015-01-09 10:44:49 EST

It was reported [1] that file versions prior to 5.22 did not limit the number of ELF notes processed, which could lead to a local resource exhaustion.

Upstream fix:
https://github.com/file/file/commit/ce90e05774dd77d86cfc8dfa6da57b32816841c4

This issue seems to be introduced here:

which ended up in 5.08 release.
