Exploitability
| CWE ID | Description |
|---|---|
| CWE-119 | The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data. |
| CWE-122 | A heap overflow condition is a buffer overflow, where the buffer that can be overwritten is allocated in the heap portion of memory, generally meaning that the buffer was allocated using a routine such as malloc(). |

AI Powered Q&A
Can you explain this vulnerability to me?
This vulnerability exists in the Axiomatic Bento4 software up to version 1.6.0-641, specifically in the function AP4_BitReader::SkipBits within the file Ap4Dac4Atom.cpp of the DSI v1 Parser component.
The issue arises when the argument n_presentations is manipulated, leading to a heap-based buffer overflow.
The attack exploiting this vulnerability must be performed locally, and a public exploit is available.
How can this vulnerability impact me? :
The vulnerability can lead to a heap-based buffer overflow, which may cause unexpected behavior such as crashes or potentially allow an attacker to execute arbitrary code with local privileges.
Since the attack requires local access, the impact is limited to users or processes with local system access.
