This vulnerability in Foxit PDF Editor is caused by improper handling of an abnormal image object that leads the renderer to enter an incorrect processing branch. During the conversion of scan lines, an invalid pointer to the image buffer is used, causing an out-of-bounds read and resulting in a crash of the application. The CVSS 3.1 base score is 6.1 (medium severity) with local attack vector, low attack complexity, no privileges required, user interaction required, unchanged scope, low confidentiality impact, no integrity impact, and high availability impact. No patch or official fix has been disclosed as of the publication date.

Successful triggering of this vulnerability causes the Foxit PDF Editor application to crash due to an out-of-bounds read. The impact is limited to availability (denial of service) with no direct confidentiality or integrity compromise indicated. Exploitation requires local access and user interaction.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, users should exercise caution when opening PDF files from untrusted sources to avoid triggering the crash. No official remediation or workaround has been provided by the vendor at this time.
