firefox: thunderbird: expat: libexpat in Expat allows attackers to trigger large dynamic memory allocations via a small document that is submitted for parsing

A memory amplification vulnerability in libexpat allows attackers to trigger excessive dynamic memory allocations by submitting specially crafted XML input. A small input 250 KiB can cause the parser to allocate hundreds of megabytes, leading to denial-of-service DoS through memory exhaustion...

Ransomware attacks and how victims respond

Welcome to this week's edition of the Threat Source newsletter. I count myself fortunate that I have never been on the receiving end of a ransomware attack. My experiences have been from research and response, never as a victim. It's a tough scenario: One day you are working or minding your own...

EUVD-2025-34724

In NetX Duo before 6.4.4, the networking support module for Eclipse Foundation ThreadX, there was a potential out of bound read issue in nxipv4packetreceive function when received an Ethernet frame with less than 4 bytes of IP packet...

Eclipse ThreadX NetX Duo 安全漏洞

Eclipse ThreadX NetX Duo is an IPv4 and IPv6 dual network stack for Eclipse ThreadX open source. A security vulnerability exists in Eclipse ThreadX NetX Duo versions prior to 6.4.4, which stems from a potential out-of-bounds read issue in the nxipv4packetreceive function when receiving Ethernet...

Toward Cybersecurity-Expert Small Language Models

Large language models LLMs are transforming everyday applications, yet deployment in cybersecurity lags due to a lack of high-quality, domain-specific models and training datasets. To address this gap, we present CyberPal 2.0, a family of cybersecurity-expert small language models SLMs ranging fr...

CVE-2023-53671

The CVE-2023-53671 issue affects the Linux kernel and is tied to SRCU behavior: when using SRCU_SIZE_SMALL, code assumed CPU 0 is always online. If a different CPU is the boot CPU (e.g., kdump with maxcpus=1), the system can hang, as observed on PowerPC where long task hangs were reported. The ro...
