### Impact ### The OCI runtime specification has a `maskedPaths` feature that allows for files or directories to be "masked" by placing a mount on top of them to conceal their contents. This is primarily intended to protect against privileged users in non-user-namespaced from being able to write to files or access directories that would either provide sensitive information about the host to containers or allow containers to perform destructive or other privileged operations on the host (examples include `/proc/kcore`, `/proc/timer_list`, `/proc/acpi`, and `/proc/keys`). `maskedPaths` can be used to either mask a directory or a file -- directories are masked using a new read-only `tmpfs` instance that is mounted on top of the masked path, while files are masked by bind-mounting the container's `/dev/null` on top of the masked path. In all known versions of runc, when using the container's `/dev/null` to mask files, runc would not perform sufficient verification that the source o...

An issue was discovered in 5.1 before 5.1.14, 4.2 before 4.2.26, and 5.2 before 5.2.8. NFKC normalization in Python is slow on Windows. As a consequence, `django.http.HttpResponseRedirect`, `django.http.HttpResponsePermanentRedirect`, and the shortcut `django.shortcuts.redirect` were subject to a potential denial-of-service attack via certain inputs with a very large number of Unicode characters. Earlier, unsupported Django series (such as 5.0.x, 4.1.x, and 3.2.x) were not evaluated and may also be affected. Django would like to thank Seokchan Yoon for reporting this issue.

Cisco Talos’ Vulnerability Discovery & Research team recently disclosed three vulnerabilities in Dell BSAFE, two in Fade In screenwriting software, and one in Trufflehog. The vulnerabilities mentioned in this blog post have been patched by their respective vendors, all in adherence to Cisco’s third-party vulnerability disclosure policy

View CSAF 1. EXECUTIVE SUMMARY CVSS v4 10.0 ATTENTION: Exploitable remotely/low attack complexity Vendor: Radiometrics Equipment: VizAir Vulnerabilities: Missing Authentication for Critical Function, Insufficiently Protected Credentials 2. RISK EVALUATION Successful exploitation of these vulnerabilities could allow attackers to manipulate critical weather parameters and runway settings, mislead air traffic control and pilots, extract sensitive meteorological data, and cause significant disruption to airport operations, leading to hazardous flight conditions. 3. TECHNICAL DETAILS 3.1 AFFECTED PRODUCTS The following versions of Radiometrics VizAir are affected: VizAir: Versions prior to 08/2025 3.2 VULNERABILITY OVERVIEW 3.2.1 MISSING AUTHENTICATION FOR CRITICAL FUNCTION CWE-306 Radiometrics VizAir is vulnerable to any remote attacker via access to the admin panel of the VizAir system without authentication. Once inside, the attacker can modify critical weather parameters such as wind sh...

A lack of server-side validation for note length in MantisBT allows attackers to permanently corrupt issue activity logs by submitting extremely long notes (tested with 4,788,761 characters). Once such a note is added: ### Impact - The entire activity stream becomes unviewable (UI fails to render). - New notes cannot be displayed, effectively breaking all future collaboration on the issue. ### Patches Fixed in 2.27.2. ### Workarounds None ### Credits Thanks to Mazen Mahmoud (@TheAmazeng) for reporting the vulnerability.

Cyberattacks are getting smarter and harder to stop. This week, hackers used sneaky tools, tricked trusted systems, and quickly took advantage of new security problems—some just hours after being found. No system was fully safe. From spying and fake job scams to strong ransomware and tricky phishing, the attacks came from all sides. Even encrypted backups and secure areas were put to the test.

Cybersecurity researchers have shed light on two different Android trojans called BankBot-YNRK and DeliveryRAT that are capable of harvesting sensitive data from compromised devices. According to CYFIRMA, which analyzed three different samples of BankBot-YNRK, the malware incorporates features to sidestep analysis efforts by first checking its running within a virtualized or emulated environment

New intelligence on Hezi Rash: See how the Kurdish group launched 350+ DDoS attacks and used DaaS platforms like EliteStress to lower entry barriers.

Brotli versions up to 1.1.0 are vulnerable to a denial of service (DoS) attack due to decompression. This issue has been patched in Brotli version 1.2.0. Additionally, this affects users who implement the Brotli decompression with Scrapy versions up to 2.13.2, leaving them vulnerable to a denial of service (DoS) attack. The protection mechanism against decompression bombs fails to mitigate the brotli variant, allowing remote servers to crash clients with less than 80GB of available memory. This occurs because brotli can achieve extremely high compression ratios for zero-filled data, leading to excessive memory consumption during decompression.

The issue has been reported by @raefko from @fuzzinglabs. Excerpts from the report: > A critical vulnerability exists in the gnark-crypto library's `Vector.ReadFrom()` function that allows an attacker to trigger arbitrary memory allocation by crafting malicious input data. An attacker can cause the verifier to attempt allocating up to 128 GB of memory with a minimal malicious input, leading to out-of-memory crashes and denial of service. > ### **Root Cause** > > > The vulnerability stems from **unchecked deserialization** of attacker-controlled length fields in the gnark-crypto library's `Vector.ReadFrom()` function. The function reads a 4-byte unsigned integer from untrusted input and directly uses it to allocate memory without any validation or bounds checking. > > ### **Vulnerable Code Path** > > ``` > User Input (Malicious Proof/Data) > ↓ > gnark Proof/Data Deserialization > ↓ > Vector.ReadFrom() (ecc/bn254/fr/vector.go:136-144) > → sliceLen := binary.BigEnd...
