Exiv2::PngImage::readMetadata() in pngimage.cpp in Exiv2 0.27.99.0 allows attackers to cause a denial of service (heap-based buffer over-read) via a crafted image file.
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.
