Adobe Bridge CC version 9.0.2 contains a use after free vulnerability that represents a critical security flaw in the software's memory management mechanisms. This vulnerability falls under the CWE-416 category, which specifically addresses use after free conditions where program code continues to reference memory after it has been freed, potentially leading to unpredictable behavior and security consequences. The flaw occurs when the application handles certain file operations or memory allocation sequences that result in objects being freed from memory while still being referenced by other parts of the code.
The technical implementation of this vulnerability stems from improper memory management within Adobe Bridge's internal processing routines. When the application processes specific file types or executes certain user interactions, it may allocate memory for objects and subsequently free them without properly nullifying the references. Attackers can exploit this by crafting malicious files or manipulating the application's workflow to trigger the use after free condition, which can result in the execution of arbitrary code or information disclosure. The vulnerability typically manifests during file handling operations, particularly when dealing with complex file formats or when multiple threads access shared memory regions.
The operational impact of this vulnerability extends beyond simple information disclosure, as it can potentially enable remote code execution in certain scenarios. An attacker who successfully exploits this use after free vulnerability could gain unauthorized access to sensitive system information, potentially leading to privilege escalation or further compromise of the affected system. The vulnerability affects Adobe Bridge CC 9.0.2 specifically, making it a targeted issue for users running this version of the software. Organizations using this version may face significant security risks, particularly in environments where Bridge is used to process untrusted files or where the application runs with elevated privileges.
Mitigation strategies for this vulnerability include immediate patching of Adobe Bridge CC to version 9.1.0 or later, which addresses the use after free condition through proper memory management updates. System administrators should implement comprehensive patch management procedures to ensure all instances of Adobe Bridge are updated across the organization. Additionally, users should be educated about the risks of processing untrusted files and should avoid opening suspicious file attachments or downloading content from unverified sources. Network segmentation and application whitelisting can provide additional layers of protection by limiting the potential attack surface and preventing unauthorized execution of malicious code. The vulnerability demonstrates the importance of proper memory management practices in software development and aligns with ATT&CK techniques related to privilege escalation and code execution through memory corruption vulnerabilities.
