ID CVE-2017-17725
Summary In Exiv2 0.26, there is an integer overflow leading to a heap-based buffer over-read in the Exiv2::getULong function in types.cpp. Remote attackers can exploit the vulnerability to cause a denial of service via a crafted image file. Note that this vulnerability is different from CVE-2017-14864, which is an invalid memory address dereference.
Vulnerable Configurations
  • Exiv2 0.26
Base: 4.3
  • Forced Integer Overflow
    This attack forces an integer variable to go out of range. The integer variable is often used as an offset such as size of memory allocation or similarly. The attacker would typically control the value of such variable and try to get it out of range. For instance the integer in question is incremented past the maximum possible value, it may wrap to become a very small, or negative number, therefore providing a very incorrect value which can lead to unexpected behavior. At worst the attacker can execute arbitrary code.
