Description Pedro Sampaio 2020-01-08 15:38:40 UTC 
In libexif, there is a possible out of bounds write due to an integer overflow. This could lead to remote escalation of privilege in the media content provider with no additional execution privileges needed. User interaction is needed for exploitation.

This bug was never fixed in Fedora. Yaakov, do you want to handle this?

(Shouldn't there have been a Fedora tracking bug?)
Comment 4 Yaakov Selkowitz 2020-06-05 00:04:41 UTC 
This is fixed by the libexif 0.6.22 update.
