In Exiv2 0.27.99.0, there is an out-of-bounds read in Exiv2::MrwImage::readMetadata() in mrwimage.cpp. It could result in denial of service.
Отчет
This issue did not affect the versions of exiv2 as shipped with Red Hat Enterprise Linux 7, and 8 as variables MemIo::Impl::size_ and MemIo::Impl::idx_ are of type long, making it impossible to trigger the integer wraparound that would lead to an out-of-bound read.
