Exiv2::Internal::PngChunk::parseTXTChunk in Exiv2 v0.26 allows remote attackers to cause a denial of service (heap-based buffer over-read) via a crafted image file, a different vulnerability than CVE-2018-10999.
An issue was discovered in Exiv2 0.26. When the data structure of the structure ifd is incorrect, the program assigns pValue to 0x0, and the value of pValue() is 0x0. TiffImageEntry::doWriteImage will use the value of pValue() to cause a segmentation fault. To exploit this vulnerability, someone must open a crafted tiff file.
A flaw was found in Exiv2 0.26, the Exiv2::Internal::printCsLensFFFF function in canonmnint.cpp allows remote attackers to cause a denial of service (invalid memory access) via a crafted file.
