CVE-2026-10705 dask HLL hyperloglog.py nunique_approx resource consumption

A flaw has been found in dask up to 3.0. Affected by this issue is the function nuniqueapprox of the file dask/dataframe/hyperloglog.py of the component HLL Handler. This manipulation causes resource consumption. The attack is possible to be carried out remotely. A high degree of complexity is...

PP-STAT: an Efficient Privacy-Preserving Statistical Analysis Framework Using Homomorphic Encryption

With the widespread adoption of cloud computing, the need for outsourcing statistical analysis to third-party platforms is growing rapidly. However, handling sensitive data such as medical records and financial information in cloud environments raises serious privacy concerns. In this paper, we...

Defending a City from Multi-Drone Attacks: a Sequential Stackelberg Security Games Approach

To counter an imminent multi-drone attack on a city, defenders have deployed drones across the city. These drones must intercept/eliminate the threat, thus reducing potential damage from the attack. We model this as a Sequential Stackelberg Security Game, where the defender first commits to a mix...

Joint Resource Optimization over Licensed and Unlicensed Spectrum in Spectrum Sharing UAV Networks against Jamming Attacks

Unmanned aerial vehicle UAV communication is of crucial importance in realizing heterogeneous practical wireless application scenarios. However, the densely populated users and diverse services with high data rate demands has triggered an increasing scarcity of UAV spectrum utilization. To tackle...

Learning-Based Cost-Aware Defense of Parallel Server Systems against Malicious Attacks

We consider the cyber-physical security of parallel server systems, which is relevant for a variety of engineering applications such as networking, manufacturing, and transportation. These systems rely on feedback control and may thus be vulnerable to malicious attacks such as denial-of-service,...

CovertAuth: Joint Covert Communication and Authentication in MmWave Systems

Beam alignment BA is a crucial process in millimeter-wave mmWave communications, enabling precise directional transmission and efficient link establishment. However, due to characteristics like omnidirectional exposure and the broadcast nature of the BA phase, it is particularly vulnerable to...

Nearly-Linear Time Private Hypothesis Selection with the Optimal Approximation Factor

Estimating the density of a distribution from its samples is a fundamental problem in statistics. Hypothesis selection addresses the setting where, in addition to a sample set, we are given $n$ candidate distributions -- referred to as hypotheses -- and the goal is to determine which one best...

Differentially Private Space-Efficient Algorithms for Counting Distinct Elements in the Turnstile Model

The turnstile continual release model of differential privacy captures scenarios where a privacy-preserving real-time analysis is sought for a dataset evolving through additions and deletions. In typical applications of real-time data analysis, both the length of the stream $T$ and the size of th...

Privacy-Aware Berrut Approximated Coded Computing Applied to General Distributed Learning

Coded computing is one of the techniques that can be used for privacy protection in Federated Learning. However, most of the constructions used for coded computing work only under the assumption that the computations involved are exact, generally restricted to special classes of functions, and...

Revert the transaction if convergence does not happen in HybridPool

Handle broccoli Vulnerability details Title: Revert the transaction if convergence does not happen in HybridPool Impact The getY and computeLiquidityFromAdjustedBalances functions use iterative approximations to calculate the output token amount or the liquidity invariant D. However, if the...

TCP/IP Sequence Prediction Blind Reset Spoofing DoS

The remote host is affected by a sequence number approximation vulnerability that allows an attacker to send spoofed RST packets to the remote host and close established connections. This may cause problems for some dedicated services BGP, a VPN over TCP, etc. C Tenable Network Security, Inc...

Multiple Vendor - TCP Sequence Number Approximation (1)

// source: https://www.securityfocus.com/bid/10183/info A vulnerability in TCP implementations may permit unauthorized remote users to reset TCP sessions. This issue affects products released by multiple vendors. Exploiting this issue may permit remote attackers to more easily approximate TCP...
