A vulnerability was found in libexif. An integer overflow when parsing the MNOTE entry data of the input file. This can cause Denial-of-Service (DoS) and Information Disclosure (disclosing some critical heap chunk metadata, even other applications' private data).
The product performs a calculation that can produce an integer overflow or wraparound when the logic assumes that the resulting value will always be larger than the original value. This occurs when an integer value is incremented to a value that is too large to store in the associated representation. When this occurs, the value may become a very small or negative number.
