Study Notes

CDCPG and Path Explosion

CDCPGs introduce relational edges linking distinct nodes or edges across different semantic domains, indicating they represent the same code entity.
Some entities lack a source or binary counterpart, complicating the relational edge sets.
Path explosion can occur when linking CPGs exhaustively from two domains, potentially hindering performance.
RANSAQ employs a lazy approach to build cross-domain portions of the CDCPG, using Vulnerability Score (VS) estimates to guide subgraph generation.
Binary symbolic analysis targets high-risk Points of Interest (POIs) identified during source analysis.

Path Exploration Strategy

Evaluation combines intra-procedural and inter-procedural graph analysis methodologies.
An updated dataset yielded 102% more relevant CVEs and 81% more related functions when comparing Libtiff and Freetype apps with previous studies.
Overall, the dataset contains 80% more CVEs per application and 29% more CVEs in total.
Gathering CVE-related data from diverse open sources, including GitHub and NVD, proves resource-intensive and time-consuming.
Manual filtering of irrelevant changes from patch commits enhances precision in vulnerability databases.

Real-World Applications and Challenges

The DARPA CHESS challenge used real-world apps with intentional vulnerabilities for assessment via reference patches.
Each application assessed includes known CVEs without using CVE data in query templates or ranking model training.
Evaluation relies on marked ground truth data linking known CVEs to patched source lines.

RANSAQ User Interface

RANSAQ presents findings through an interactive web interface, ranking POIs based on their VS.
Each POI includes CWE classification, vulnerability description, source file name, and a unique identification number.
Detailed views for each POI display function names, line numbers, code snippets, and complexity scores influenced by various metrics.
Example vulnerabilities identified include a stack-based buffer overflow (CVE-2008-0671) in TinTin++ with a CVSS score of 10.0 and a heap-based buffer overflow (CVE-2021-3156) in Sudo with a score of 7.8.
Both vulnerabilities exist within large codebases, showcasing the effectiveness of RANSAQ in highlighting POIs for code reviews.
