Description

This security bulletin contains information about 2 vulnerabilities.

1) Memory leak (CVE-ID: CVE-2018-11037)

CWE-ID: CWE-401 - Missing release of memory after effective lifetime

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

The vulnerability allows a remote attacker to obtain potentially sensitive information or perform a denial of service (DoS) attack.

The vulnerability exists due to memory leak in Exiv2::PngImage::printStructure function in pngimage.cpp. A remote attacker can trick the victim into opening a specially crafted input and gain access to arbitrary data or perform a denial of service attack.

CWE-ID: CWE-190 - Integer overflow

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

The vulnerability exists due to integer overflow in Exiv2 through 0.27.1 due to PngImage::readMetadata mishandles a chunkLength - iccOffset subtraction. A remote attacker can create a crafted PNG image file, trigger integer overflow and perform denial of service (DoS) attack.
