Description Sam Fowler 2018-05-16 02:13:43 EDT

In types.cpp in Exiv2 0.26, a large size value may lead to a SIGABRT during an attempt at memory allocation for an Exiv2::Internal::PngChunk::zlibUncompress call.

Created exiv2 tracking bugs for this issue:

Affects: fedora-all [bug 1578661]

Comment 3 Pedro Yóssis Silva Barbosa 2018-05-24 16:20:25 EDT

Upstream patch:

https://github.com/Exiv2/exiv2/pull/316/files

For RHEL 6 and 7 the code parts are in src/pngimage.cpp (not in src/pngchunk_int.cpp).
