UBUNTU-CVE-2023-0216

An invalid pointer dereference on read can be triggered when an application tries to load malformed PKCS7 data with the d2iPKCS7, d2iPKCS7bio or d2iPKCS7fp functions. The result of the dereference is an application crash which could lead to a denial of service attack. The TLS implementation in...

Attacking Machine Learning Systems

The field of machine learning ML security--and corresponding adversarial ML--is rapidly advancing as researchers develop sophisticated techniques to perturb, disrupt, or steal the ML model or data. It’s a heady time; because we know so little about the security of these systems, there are many...
