The vulnerability of the Sampling Route Record Daemon (SRRD) in the Juniper Networks Junos OS operating system allows a hacker to cause a service failure.

The vulnerability of the Sampling Route Record Daemon SRRD in the Juniper Networks Junos OS operating system is related to a lack of mechanisms for encoding or shielding outgoing data. Exploiting this vulnerability can allow a malicious actor to trigger a service failure...

Reveal-Or-Obscure: a Differentially Private Sampling Algorithm for Discrete Distributions

We introduce a differentially private DP algorithm called reveal-or-obscure ROO to generate a single representative sample from a dataset of $n$ observations drawn i.i.d. from an unknown discrete distribution $P$. Unlike methods that add explicit noise to the estimated empirical distribution, ROO...

Provable Secure Steganography Based on Adaptive Dynamic Sampling

The security of private communication is increasingly at risk due to widespread surveillance. Steganography, a technique for embedding secret messages within innocuous carriers, enables covert communication over monitored channels. Provably Secure Steganography PSS is state of the art for making...

Improving Statistical Privacy by Subsampling

Differential privacy DP considers a scenario, where an adversary has almost complete information about the entries of a database This worst-case assumption is likely to overestimate the privacy thread for an individual in real life. Statistical privacy SP denotes a setting where only the...

CVE-2025-30657

An Improper Encoding or Escaping of Output vulnerability in the Sampling Route Record Daemon SRRD of Juniper Networks Junos OS allows an unauthenticated, network-based attacker to cause a Denial-of-Service DoS.
