CVE-2025-29954: Windows Lightweight Directory Access Protocol (LDAP) Denial of Service Vulnerability

**According to the CVSS metric, the attack complexity is high (AC:H). What does that mean for this vulnerability?** Successful exploitation of this vulnerability requires an attacker to invest time in repeated exploitation attempts through sending constant or intermittent data.

CVE-2025-30394: Windows Remote Desktop Gateway (RD Gateway) Denial of Service Vulnerability

Sensitive data storage in improperly locked memory in Remote Desktop Gateway Service allows an unauthorized attacker to deny service over a network.

GHSA-7c85-87cp-mr6g: LlamaIndex Vulnerable to Denial of Service (DoS)

A Denial of Service (DoS) vulnerability has been identified in the KnowledgeBaseWebReader class of the run-llama/llama_index project, affecting version ~ latest(v0.12.15). The vulnerability arises due to inappropriate secure coding measures, specifically the lack of proper implementation of the max_depth parameter in the get_article_urls function. This allows an attacker to exhaust Python's recursion limit through repeated function calls, leading to resource consumption and ultimately crashing the Python process.

GHSA-gjh7-p2fx-99vx: Rack has an Unbounded-Parameter DoS in Rack::QueryParser

## Summary `Rack::QueryParser` parses query strings and `application/x-www-form-urlencoded` bodies into Ruby data structures without imposing any limit on the number of parameters, allowing attackers to send requests with extremely large numbers of parameters. ## Details The vulnerability arises because `Rack::QueryParser` iterates over each `&`-separated key-value pair and adds it to a Hash without enforcing an upper bound on the total number of parameters. This allows an attacker to send a single request containing hundreds of thousands (or more) of parameters, which consumes excessive memory and CPU during parsing. ## Impact An attacker can trigger denial of service by sending specifically crafted HTTP requests, which can cause memory exhaustion or pin CPU resources, stalling or crashing the Rack server. This results in full service disruption until the affected worker is restarted. ## Mitigation - Update to a version of Rack that limits the number of parameters parsed, or - ...
