Overview

CVE-2017-11613 is a medium-severity vulnerability. It was published on July 26, 2017 and has a CVSS 3.0 base score of 6.5 (MEDIUM).

This vulnerability has a CVSS 3.0 base score of 6.5, rated MEDIUM. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.

Technical description

In LibTIFF 4.0.8, there is a denial of service vulnerability in the TIFFOpen function. A crafted input will lead to a denial of service attack. During the TIFFOpen process, td_imagelength is not checked. The value of td_imagelength can be directly controlled by an input file. In the ChopUpSingleUncompressedStrip function, the _TIFFCheckMalloc function is called based on td_imagelength. If we set the value of td_imagelength close to the amount of system memory, it will hang the system or trigger the OOM killer.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
