The tEXtToDataBuf function in pngimage.cpp in Exiv2 through 0.26 allows remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact via a crafted file.
In Exiv2 0.26, there is an out-of-bounds read in Exiv2::Internal::binaryToString in image.cpp. It could result in denial of service or information disclosure.
Integer overflow in exif.cpp in exiv2 library allows context-dependent attackers to execute arbitrary code via a crafted EXIF file that triggers a heap-based buffer overflow.
