The HTTP/2 front-end of the Zephyr HTTP server aliased connection receive state as a scratch output. In subsys/net/lib/http/http_server_http2.c, handle_http2_static_fs_resource() passed &client->data_len as the file_size out-parameter of http_server_find_file(). client->data_len is the count of unprocessed bytes remaining in the fixed-size per-connection receive buffer client->buffer[CONFIG_HTTP_SERVER_CLIENT_BUFFER_SIZE] (256 bytes by default), an invariant every frame handler and the socket receive path rely on. Serving any static file therefore replaced that bounded value with the file's on-disk size, and nothing resets it afterwards. The defect is reached by an unauthenticated HTTP/2 GET for any file under the web root, in applications that register a static-filesystem resource (HTTP_RESOURCE_TYPE_STATIC_FS) with CONFIG_FILE_SYSTEM=y; CONFIG_HTTP_SERVER_VERSION_2 is enabled by default and no TLS or credentials are required on this path. Once client->data_len exceeds the buffer size, the frame dispatch loop in subsys/net/lib/http/http_server_core.c keeps parsing past the end of the received data, and the peer controls the bytes at client->cursor, so it can choose which fabricated frame the state machine consumes next by appending bytes after its request. The inflated length defeats the only guards on the buffer. parse_http_frame_header() and the per-frame handlers read and skip up to a 24-bit frame length beyond the buffer (out-of-bounds read); the compaction memmove(client->buffer, client->cursor, client->data_len) at the end of request handling copies the file-size number of bytes into the 256-byte buffer, overflowing the rest of struct http_client_ctx — including the current_detail/current_stream pointers, the parser_settings function-pointer table and the inactivity_timer work handler — and the adjacent client contexts in static memory; and the subsequent zsock_recv(client->fd, client->buffer + client->data_len, sizeof(client->buffer) - client->data_len, 0) underflows its size argument, writing attacker-supplied data of attacker-chosen length out of bounds. The impact is remote memory corruption in the server's single address space: at minimum a crash or hang of the device, and plausibly control-data overwrite leading to code execution. The HTTP/1 and HTTP/3 static-filesystem handlers already used a local variable and are unaffected; the fix makes the HTTP/2 handler use a local size_t file_size as well.

A deferred-callback use-after-destroy in Node.js TLS server handshake handling allows a remote, unauthenticated attacker to terminate the server process. When a TLS server uses any of the SNICallback, OCSPRequest, newSession, or resumeSession hooks, or server.addContext(), the corresponding OpenSSL callbacks are deferred, and the deferred code does not handle the underlying socket being destroyed between scheduling and execution. By sending a client hello that reaches the vulnerable path (for example, no SNI together with an OCSP request) followed by padding and a socket FIN, an attacker makes OpenSSL deliver the client hello and the end-of-file in the same tick, so the socket is destroyed before the deferred callback runs and the process raises an uncaught exception instead of emitting an 'error' event. This vulnerability affects Node.js 26.x and 24.x.

An access of uninitialized pointer vulnerability in the nfsd in Synology DiskStation Manager (DSM) before 7.3.2-86009-5 and 7.4.1-90080-1 allows remote attackers to conduct denial-of-service attacks.

The policy RPC stubs in kadmin/server/server_stubs.c in MIT Kerberos 5 (aka krb5) 1.5.3 and later do not reject a NULL policy name decoded by xdr_nullstring(), which allows remote authenticated users to cause a denial of service (kadmind crash via NULL pointer dereference) by sending a policy request with an empty policy name that reaches authorization checks or logging code.

A use-after-free in the replication component of MongoDB Server can occur when a newly elected replica set primary completes catch-up. The condition can be caused by requests that do not require authentication, and may result in the server terminating unexpectedly or, under certain conditions, arbitrary code execution in the context of the server process. Replica set members are affected, including the shard and config server replica set members of sharded clusters; standalone mongod instances are not.

Operation on a dropped index in PostgreSQL REINDEX CONCURRENTLY allows an object creator to execute arbitrary code as the operating system user running the database, via an index expression that issues DROP INDEX. Versions before PostgreSQL 18.7, 17.12, 16.16, 15.20, and 14.25 are affected.

A use-after-free in the time-series collection component of MongoDB Server can occur when the server validates a time-series bucket document during a write. The condition can be caused by an authenticated user with privileges to write bucket documents directly, and may result in the server terminating unexpectedly or, under certain conditions, arbitrary code execution in the context of the server process.

Heap-based buffer overflow in PostgreSQL foreign batch inserts allows a foreign server to execute arbitrary code, via reporting that it inserted more rows than the server supplied. postgres_fdw can legitimately encounter this when a rule on the remote table expands an INSERT into additional rows. Versions before PostgreSQL 18.7, 17.12, 16.16, 15.20, and 14.25 are affected.

Heap-based buffer overflow in PostgreSQL tsvector_delete() allows a database user to execute arbitrary code as the operating system user running the database, via a tsvector whose lexeme data uses a nonstandard but valid ordering that requires additional alignment padding in the result. Versions before PostgreSQL 18.7, 17.12, 16.16, 15.20, and 14.25 are affected.

Heap-based buffer overflow in PostgreSQL ts_rank_cd() may allow a database user to execute arbitrary code as the operating system user running the database, via an invalid tsvector containing duplicate positions. Versions before PostgreSQL 18.7, 17.12, 16.16, 15.20, and 14.25 are affected.

Type confusion in PostgreSQL allows an object creator to execute arbitrary code as the operating system user running the database, via ALTER ... SET DATA TYPE primarily. Other DDL attack routes exist, such as "ALTER TABLE ... ADD COLUMN; ROLLBACK; ALTER TABLE ... ADD COLUMN". The system had inadequate tracking of typed values, and values were not self-identifying. Stale values could appear in data dictionary entries, PL/pgSQL variables, and many other parts of the system. PostgreSQL Versions before PostgreSQL 18.7, 17.12, 16.16, 15.20, and 14.25 are affected.

Use after free in the PostgreSQL dblink extension allows an object creator to execute arbitrary code as the operating system user running the database, via type conversion code that re-enters dblink and closes a connection whose results an outer dblink call is reading. Versions before PostgreSQL 18.7, 17.12, 16.16, 15.20, and 14.25 are affected.

Type confusion in PostgreSQL plpgsql record-field assignment allows an object creator to execute arbitrary code as the operating system user running the database, via a reentrant domain CHECK that changes a RECORD variable's row type while a value is being cast. Versions before PostgreSQL 18.7, 17.12, 16.16, 15.20, and 14.25 are affected.
