Technical details

An Access of Uninitialized Pointer vulnerability (CWE-824) exists in Adobe FrameMaker versions 2022.8 and earlier. The flaw occurs when the application attempts to access a pointer that has not been properly initialized, potentially leading to the disclosure of sensitive memory contents. The attack vector is local, requiring a user to open a maliciously crafted file (User Interaction: Required). This vulnerability can result in a high impact on confidentiality but does not directly affect integrity or availability. Adobe has addressed this issue in newer versions of the software.
