Acrobat Reader is affected by a Heap-based Buffer Overflow vulnerability that could lead to disclosure of sensitive memory. An attacker could leverage this vulnerability to disclose sensitive information. Exploitation of this issue requires user interaction in that a victim must open a malicious file.
AnalysisAI
Heap-based buffer overflow in Adobe Acrobat Reader (versions ≤26.002.21900 and Acrobat 2024 ≤24.001.30383) allows an attacker to disclose sensitive memory contents by delivering a crafted PDF file to a victim. The overflow is triggered during file parsing and results in out-of-bounds read of heap memory, enabling confidentiality compromise without integrity or availability impact. …
