Description
This security bulletin contains information about 3 vulnerabilities.
1) Memory corruption (CVE-ID: CVE-2017-17723)
CWE-ID: CWE-119 - Memory corruption
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a remote unauthenticated attacker to cause DoS condition on the target system.
The weakness exists in the Exiv2::Image::byteSwap4 function of image.cpp due to boundary error. A remote attacker can send a specially crafted TIFF image file, trick the victim into opening it and cause the service to crash.
2) Memory corruption (CVE-ID: CVE-2017-17725)
CWE-ID: CWE-119 - Memory corruption
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:P/U:Clear
The vulnerability allows a remote unauthenticated attacker to cause DoS condition on the target system.
The weakness exists in the Exiv2::getULong function of types.cpp due to boundary error. A remote attacker can send a specially crafted image file, trick the victim into opening it and cause the service to crash.
3) Segmentation fault (CVE-ID: CVE-2018-5772)
CWE-ID: CWE-20 - Improper input validation
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to uncontrolled recursion in the Exiv2::Image::printIFDStructure function in the image.cpp file. A remote attacker can trick the victim into opening a specially crafted tif input, trigger segmentation fault and perform a denial of service attack.
