Improper resource allocation - Buffer overflow In exiv2
Description
A flaw was found in exiv2. A flawed bounds checking in the jp2Image.cpp:doWriteMetadata function leads to a heap-based buffer overflow. This flaw allows an attacker who can provide a malicious image to an application using the exiv2 library, to write data out of bounds and potentially execute code. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.
