Description

This security bulletin contains information about 4 vulnerabilities.


1) Infinite loop (CVE-ID: CVE-2019-9143)

CWE-ID: CWE-835 - Loop with Unreachable Exit Condition ('Infinite Loop')

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 attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to infinite loop in Exiv2::Image::printTiffStructure() function in the file image.cpp. A remote attacker can consume all available system resources via a specially crafted image and cause denial of service conditions.


2) Infinite loop (CVE-ID: CVE-2019-9144)

CWE-ID: CWE-835 - Loop with Unreachable Exit Condition ('Infinite Loop')

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 attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to infinite loop in BigTiffImage::printIFD() function in the file bigtiffimage.cpp. A remote attacker can consume all available system resources via a specially crafted image and cause denial of service conditions.


3) Resource exhaustion (CVE-ID: CVE-2018-17581)

CWE-ID: CWE-400 - Resource exhaustion

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to application does not properly control consumption of internal resources caused by excessive stack consumption due to a recursive function within the CiffDirectory::readDirectory() function in crwimage_int.cpp. A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.


4) Uncaught Exception (CVE-ID: CVE-2017-11591)

CWE-ID: CWE-248 - Uncaught Exception

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to a floating point exception in the Exiv2::ValueType function in Exiv2. A remote attacker can pass a specially crafted image to the application and perform a denial of service (DoS) attack.
