Technical ContextAI · show details
This vulnerability is classified as Integer Overflow (CWE-190), which allows attackers to cause unexpected behavior through arithmetic overflow. An exploitable vulnerability exists in the object stream parsing functionality of Nitro Software, Inc.’s Nitro Pro 13.13.2.242 when updating its cross-reference table. When processing an object stream from a PDF document, the application will perform a calculation in order to allocate memory for the list of indirect objects. Due to an error when calculating this size, an integer overflow may occur which can result in an undersized buffer being allocated. Later when initializing this buffer, the application can write outside its bounds which can cause a memory corruption that can lead to code execution. A specially crafted document can be delivered to a victim in order to trigger this vulnerability. Affected products include: Gonitro Nitro Pro.

SSVC AssessmentENISA
Priority Score
Attack Technique
A buffer overflow occurs when a program writes more data to a memory buffer than it was allocated to hold, causing the excess data to spill into adjacent memory regions.
Integer overflow occurs when an arithmetic operation produces a result that exceeds the maximum value a given integer type can store.
Remote Code Execution represents the critical moment when an attacker successfully runs arbitrary code on a target system without physical access.
