Description Laura Pardo 2018-05-17 14:26:12 EDT 
An issue was discovered in Exiv2 0.26. The readMetadata function in jp2image.cpp allows remote attackers to cause a denial of service (SIGABRT) by triggering an incorrect Safe::add call.

Comment 1 Laura Pardo 2018-05-17 14:29:22 EDT 
Created exiv2 tracking bugs for this issue:

Affects: fedora-all [bug 1579486]
Comment 6 Pedro Yóssis Silva Barbosa 2018-05-18 17:19:48 EDT 
In RHEL 7, the PoC triggered a SIGABRT. Thus, this bug may have some deny of service effect (although not confirmed by upstream so far).
Comment 7 Pedro Yóssis Silva Barbosa 2018-05-21 06:04:05 EDT 
The SIGABRT happens just because the exiv2 app is not catching an intended throwed exception.
