AI-suggested
Until official patches are released, organizations should implement several specific mitigations: 1) Restrict the opening of InCopy files to trusted sources only, using email filtering and endpoint controls to block suspicious attachments. 2) Employ application whitelisting to prevent execution of unauthorized code spawned by exploitation attempts. 3) Educate users about the risks of opening unsolicited or unexpected InCopy files, emphasizing cautious handling of attachments. 4) Monitor endpoint behavior for anomalies such as unexpected process creation or memory corruption indicators related to InCopy. 5) Use sandboxing or isolated environments for opening untrusted InCopy files to contain potential exploitation. 6) Keep all other software and operating systems up to date to reduce the risk of chained exploits. 7) Prepare incident response plans to quickly address any suspected exploitation. Once Adobe releases patches, prioritize their deployment across all affected systems to eliminate the vulnerability.
Description
InCopy versions 20.4, 19.5.4 and earlier are affected by a Heap-based Buffer Overflow vulnerability that could result in arbitrary code execution in the context of the current user. Exploitation of this issue requires user interaction in that a victim must open a malicious file.
