AI-suggested

European organizations should immediately implement the following specific measures: 1) Identify and inventory all instances of Foxit PDF Reader version 2024.4.0.27683 in their environment. 2) Until an official patch is released, restrict or disable the opening of PRC files within PDFs by configuring Foxit Reader settings or using application control policies. 3) Employ endpoint protection solutions capable of detecting and blocking exploitation attempts targeting this vulnerability. 4) Educate users about the risks of opening unsolicited or suspicious PDF attachments, emphasizing caution with files containing embedded 3D content. 5) Use network-level controls to block access to known malicious URLs that could host exploit PDFs. 6) Monitor logs and endpoint behavior for signs of exploitation attempts, such as unusual process activity or memory access violations. 7) Consider deploying sandboxing solutions to safely open PDFs in isolated environments. 8) Stay alert for vendor updates and apply patches promptly once available. 9) Implement strict email filtering to reduce phishing emails carrying malicious PDFs. These targeted actions go beyond generic advice by focusing on the specific vector (PRC file parsing) and the software version affected.

Description

Foxit PDF Reader PRC File Parsing Out-Of-Bounds Read Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Foxit PDF Reader. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the parsing of PRC files. The issue results from the lack of proper validation of user-supplied data, which can result in a read past the end of an allocated buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-26772.
