pyasn1: pyasn1 Vulnerable to Denial of Service via Unbounded Recursion

An unbounded recursion flaw has been discovered in the pypi pyasn1 library. This uncontrolled recursion occurs when decoding ASN.1 data with deeply nested structures. An attacker can supply a crafted payload containing nested SEQUENCE 0x30 or SET 0x31 tags with Indefinite Length 0x80 markers. Thi...

JLSEC-2026-393

curl 7.84.0 supports "chained" HTTP compression algorithms, meaning that a serverresponse can be compressed multiple times and potentially with different algorithms. The number of acceptable "links" in this "decompression chain" was unbounded, allowing a malicious server to insert a virtually...

Security Bulletin: Denial of Service in urllib3 via Unbounded Decompression of Redirect Responses

Summary urllib3 is an HTTP client library for Python. urllib3's streaming API is designed for the efficient handling of large HTTP responses by reading the content in chunks, rather than loading the entire response body into memory at once. urllib3 can perform decoding or decompression based on t...

Security Bulletin:urllib3 Unbounded Decompression Chain Enables Denial of Service

Summary urllib3 is a user-friendly HTTP client library for Python. Starting in version 1.24 and prior to 2.6.0, the number of links in the decompression chain was unbounded allowing a malicious server to insert a virtually unlimited number of compression steps leading to high CPU usage and massiv...

CVE-2026-6948

CVE-2026-6948 affects Velociraptor servers prior to version 0.76.4, where the VQLResponse Result-Set Writer can allocate memory unboundedly in the agent control channel. A compromised Velociraptor client can trigger an Out-Of-Memory (OOM) condition, crashing the server by sending crafted messages...

CVE-2026-6948 Unbounded Memory Allocation in VQLResponse Result-Set Writer

Velociraptor versions prior to 0.76.4 contain a resource exhaustion vulnerability in the server's agent control channel. This allows a compromised or rogue Velociraptor client to crash the server via out-of-memory OOM by sending crafted messages through the normal client communication channel...
