CVE-2019-17402 (NVD)

2019-10-09

Exiv2 0.27.2 allows attackers to trigger a crash in Exiv2::getULong in types.cpp when called from Exiv2::Internal::CiffDirectory::readDirectory in crwimage_int.cpp, because there is no validation of the relationship of the total size to the offset and size.

Products Ubuntu_linux, Debian_linux, Exiv2
Type Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') (CWE-120)
First patch - None (likely due to unavailable code)
