rosbridge_library Protocol.incoming() quadratic CPU cost in JSON fallback

rosbridge_library's Protocol.incoming() has quadratic CPU cost in its JSON fallback, enabling denial of service via crafted messages.

Evgenios Gkritsis disclosed an algorithmic-complexity defect in rosbridge_suite's rosbridge_library Protocol.incoming() JSON fallback path, classified as CWE-407/CWE-1050. The flaw exists in the current ros2 branch and was not removed by PR #1199, having been present since the fallback was introduced. Crafted input can drive quadratic CPU cost and cause denial of service.

Cisco Secure Firewall Management Center Software Java Deserialization Remote Code Execution Vulnerability

Cisco fixed an unauthenticated Java deserialization RCE in FMC's External Database Access feature allowing root command execution via a TCP port.

Insecure deserialization of a user-supplied Java byte stream in Cisco Secure Firewall Management Center's External Database Access feature lets an unauthenticated remote attacker execute arbitrary commands and elevate to root. Exploitation requires sending a crafted serialized stream to a specific TCP port from a host configured in the external database access list. Cisco has released software updates.

VU#369093: MLflow dspy and statsmodels flavors bypass pickle deserialization control

CERT/CC warns MLflow's dspy and statsmodels flavors bypass the MLFLOW_ALLOW_PICKLE_DESERIALIZATION control, enabling remote code execution.

CERT/CC vulnerability note VU#369093 describes a flaw in MLflow 3.12.0 where the dspy flavor conditionally applies the pickle deserialization safety control based only on the model path's .pkl extension, while the statsmodels flavor skips the check entirely, permitting arbitrary code execution via malicious pickle payloads even when users disallow pickle. The statsmodels flavor is patched in versions 3.15.0 and later, but no dspy fix exists yet, so users should avoid loading models through that flavor. Exploitation requires write access to any location from which a user obtains MLflow models.

Subgroup Packing for Batched PASTA Transciphering

Interleaved subgroup packing cuts PASTA homomorphic transciphering server cost by a median 1.60x at the expense of remaining noise capacity.

The paper studies how record word layout affects the cost of PASTA transciphering, where a server converts symmetrically encrypted records into homomorphic ciphertexts. A subgroup layout interleaves records so cyclic shifts preserve positions, reducing required displacements from 255 to 128 versus contiguous packing. In HElib across twelve paired corpora under six homomorphic keys, the median direct-to-subgroup server cost ratio is 1.60 including fresh generation, conversion, and two queries, but with less remaining noise capacity.

ClearFake WebDAV infection chain delivers Amatera stealer, ZigCryptoStealer, and NetSupport Manager

Cisco Talos investigated DLL executions named 'verification.google' via WebDAV UNC paths at a Ukrainian government organization, tracking the actor as UAT-10820 and assessing with moderate confidence the activity is Russian and opportunistic rather than targeted. The infection chain uses ClearFake JavaScript injected via a Cloudflare Worker, EtherHiding storage on BNB Smart Chain contracts, and a ClickFix fake Google CAPTCHA prompt to deliver Amatera stealer. Secondary payloads differ by C2: one loader deploys ZigCryptoStealer with a Go reverse TCP proxy and a vulnerable driver that kills EDR, while the other installs an unauthorized NetSupport Manager with a Russia-based C2. Similar Amatera chains were separately documented by Malwarebytes and Blackpoint Cyber, but with no shared infrastructure.
