Technical details

An integer underflow (CWE-191) vulnerability exists in Adobe FrameMaker versions 2022.8 and earlier. The flaw occurs during the processing of specially crafted files, where a wrap-around error can lead to memory corruption. An attacker can exploit this by delivering a malicious file to a victim; upon opening the file, the vulnerability triggers, potentially allowing arbitrary code execution in the context of the current user. The attack requires user interaction (UI:R) and local delivery (AV:L), but provides high impact to confidentiality, integrity, and availability. Adobe has addressed this in version 2022.9.
