CVE-2005-0045
HighSummary
The Server Message Block (SMB) implementation for Windows NT 4.0, 2000, XP, and Server 2003 does not properly validate certain SMB packets, which allows remote attackers to execute arbitrary code via Transaction responses containing (1) Trans or (2) Trans2 commands, aka the 'Server Message Block Vulnerability,' and as demonstrated using Trans2 FIND_FIRST2 responses with large file name length fields.
Risk Assessment
The risk for the organization includes the possibility of remote code execution without authentication, which could lead to data theft, malware installation, or further propagation of the attack within the network.
Recommendation
It is recommended to immediately apply the security patches provided by Microsoft for this vulnerability (MS05-011) and restrict access to SMB ports (139/TCP, 445/TCP) from trusted networks.

Under specific conditions, an attacker can register an attacker-controlled FIDO2 credential against a target account and then authenticate as that user. This issue affects on-premises deployments only.

In Submariner's cert-auth mode, connection configuration is built from unvalidated free-form strings from the CRD. A malicious cluster can publish a CableName with newlines and ipsec.conf directives, allowing injection of arbitrary configuration or command execution via leftupdown hooks, leading to remote code execution as root on the gateway node.

In the PREVAIL eBPF verifier before version 0.2.4, the abstract transformer treats writes through a T_CTX-typed base register as a silent no-op. An attacker can craft an eBPF program that overwrites a context field, reloads it as T_PACKET, and dereferences an attacker-controlled address, and PREVAIL will report the program as safe.
- CVE-2026-53670Critical
In the PREVAIL eBPF verifier before version 0.2.4, EbpfTransformer::add() silently skips offset-variable updates when the destination register carries a non-singleton typeset. Subsequent bounds checks use the stale offset and accept out-of-bounds memory accesses, so a crafted BPF program passes verification even though it would corrupt memory at runtime.

Joro before version 1.1.1 in default proxy mode exposes a local API on 127.0.0.1:9090 with no authentication and wildcard CORS. A malicious website can reach privileged endpoints, including uploading a native plugin and triggering a restart, leading to unauthenticated remote code execution as the operator's user.

A vulnerability in the Silicon One integration for Cisco Nexus 9000 Series Switches allows an unauthenticated remote attacker to execute code with root privileges. TCP ports 43210 and 43211 are accessible in the default L3 VRF, and crafted input can lead to code execution or crash of the S1HAL process causing device reload.

- CVE-2026-82955Critical
In the current development version of Eclipse aeriOS, the KrakenD instance in the API Gateway had disable_jwk_security hard-coded to true, disabling TLS certificate verification when retrieving JWKS. This could allow an attacker to intercept communication and provide a malicious JWKS, compromising token validation. The issue has been fixed by making the parameter configurable and defaulting to false.
