Descrição técnica

FastNetMon is a high-performance DDoS detector and sensor. In version 1.2.9 and earlier, FastNetMon's IPv6 top-talkers screen-draw thread in draw_table_ipv6() in src/fastnetmon_logic.cpp iterates ipv6_host_counters.average_speed_map without holding counter_map_mutex while recalculate_speed() inserts new keys and may rehash the same map. The race requires networks_list to include the targeted IPv6 range. It causes confirmed undefined behavior under load; a process crash is plausible but was not observed, so reliable denial of service has not been established. No fixed release is available as of this review.

———The Model Context Protocol TypeScript SDK provides TypeScript client and server implementations of the Model Context Protocol. From 2.0.0 until 2.3.0 in @modelcontextprotocol/server, applications that shared one stateless HTTP transport or one McpServer or Server instance among multiple clients could deliver responses and notifications to the wrong client. The affected surface is an MCP server reached over HTTP by multiple clients. The trigger is reuse of one stateless transport or server instance. Messages were associated with a connection using only the JSON-RPC request identifier. SDK clients start request identifiers at zero, so collisions occur in normal operation. Cross-client delivery exposes one client's responses and notifications to another client. The issue requires an HTTP endpoint reachable by more than one client and an application that constructs the server or transport once at startup instead of once per request or session. stdio servers and factory-created per-call servers are not affected. Upgrading causes reused instances to fail and therefore requires an application code change. This issue is fixed in @modelcontextprotocol/server 2.3.0.6h CVE-2026-1031127.5 ALT

——0A flaw was found in the authentication session handling of the keycloak-services component in Keycloak. The issue occurs because the system fails to verify if an authenticator is valid for the current authentication flow when switching between the standard authentication path and the reset credentials path. An authenticated attacker can exploit this by triggering a race condition during the credential reset process to associate their successful authentication state with another user's session. This can result in the attacker gaining full access to the victim's account and changing their password.11h CVE-2026-1219635.9 MÉD

——7FreeRDP before 3.32.2 contains a use-after-free vulnerability in the asynchronous dynamic rdpsnd channel that allows malicious RDP servers to trigger freed callback access by closing the channel with queued audio PDUs. Attackers can send a training PDU then close the channel so the playback thread reads the freed callback in rdpsnd_virtual_channel_write, crashing the client.9h CVE-2026-1219615.9 MÉD

——7FreeRDP before 3.32.2 contains a use-after-free vulnerability in the freerdp-proxy DRDYNVC tracker when intercepting the drdynvc channel. A malicious target server can repeatedly send CREATE_REQUEST_PDU for an active channel id, racing front DATA handling to free a borrowed context and crash the proxy process.9h CVE-2026-1219577.5 ALT

——7FreeRDP before 3.32.2 contains a use-after-free vulnerability that allows malicious RDP servers to corrupt client memory by racing the RDPGFX ResetGraphics handler against the planar bitmap decoder. Attackers can send ResetGraphics while concurrently sending compressed bitmaps of 32 bpp or more to trigger heap use-after-free or out-of-bounds read/write on shared planar buffers.9h CVE-2026-1212308.3 ALT
