AI Powered Q&A
Can you explain this vulnerability to me?
This vulnerability is an out-of-bounds read in the RLECodec::DecodeByStreams functionality of Grassroot DICOM 3.024. It occurs when processing a specially crafted DICOM file, which can cause the program to read memory outside the intended buffer, potentially leaking heap data. An attacker can exploit this by providing a malicious DICOM file to trigger the vulnerability.
How can this vulnerability impact me? :
This vulnerability can lead to leaking sensitive heap data, which may include confidential information. Because it has high impact on confidentiality, integrity, and availability, an attacker exploiting this could compromise system data, affect system integrity, and potentially disrupt operations.
