Description Laura Pardo 2018-05-17 18:26:12 UTC 
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 18:29:22 UTC 
Created exiv2 tracking bugs for this issue:

Affects: fedora-all [bug 1579486]
Comment 6 Pedro Yóssis Silva Barbosa 2018-05-18 21:19:48 UTC 
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 10:04:05 UTC 
The SIGABRT happens just because the exiv2 app is not catching an intended throwed exception.
Comment 8 errata-xmlrpc 2019-08-06 12:14:36 UTC
