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...

curl: PROTOCOL-LEVEL: Persistent UDP Amplification and Cache Poisoning via Alt-Svc Logic Flaw
Summary A structural logic flaw in the libcurl Alt-Svc header parser allows attack attributes specifically persist and max-age to "leak" from one service definition to another. We have successfully chained this logic bug with curl's HTTP/3 QUIC support to demonstrate a Persistent UDP Amplificatio...
CVE-2025-34469 Cowrie < 2.9.0 Unrestricted wget/curl Emulation Enables SSRF-Based DDoS Amplification
Cowrie versions prior to 2.9.0 contain a server-side request forgery SSRF vulnerability in the emulated shell implementation of wget and curl. In the default emulated shell configuration, these command emulations perform real outbound HTTP requests to attacker-supplied destinations. Because no...

Security without Detection: Economic Denial As a Primitive for Edge and IoT Defense
Detection-based security fails against sophisticated attackers using encryption, stealth, and low-rate techniques, particularly in IoT/edge environments where resource constraints preclude ML-based intrusion detection. We present Economic Denial Security EDS, a detection-independent framework tha...
Asymmetric Resource Consumption (Amplification)
Overview Affected versions of this package are vulnerable to Asymmetric Resource Consumption Amplification via the Schema.load method of the error storage utility, when handling input with the many parameter set to True. An attacker can cause excessive CPU consumption by submitting a moderately...
Server-side Request Forgery (SSRF)
Overview cowrie is a Cowrie SSH/Telnet Honeypot. Affected versions of this package are vulnerable to Server-side Request Forgery SSRF via the emulation of wget and curl commands in shell mode. An attacker can cause the system to send arbitrary HTTP requests to external hosts by repeatedly invokin...
GHSA-83JG-M2PM-4JXJ Cowrie has a SSRF vulnerability in wget/curl emulation enabling DDoS amplification
Summary A Server-Side Request Forgery SSRF vulnerability in Cowrie's emulated shell mode allows unauthenticated attackers to abuse the honeypot as an amplification vector for HTTP-based denial-of-service attacks against arbitrary third-party hosts. Details When Cowrie operates in emulated shell...

Sigstore Timestamp Authority allocates excessive memory during request parsing
Impact Excessive memory allocation Function api.ParseJSONRequest currently splits via a call to strings.Split an optionally-provided OID which is untrusted data on periods. Similarly, function api.getContentType splits the Content-Type header which is also untrusted data on an application string...
Fulcio allocates excessive memory during token parsing
Function identity.extractIssuerURL currently splits via a call to strings.Split its argument which is untrusted data on periods. As a result, in the face of a malicious request with an invalid OIDC identity token in the payload containing many period characters, a call to extractIssuerURL incurs...
