postgresql: PostgreSQL libpq: Buffer overflow allows server superuser to overwrite client stack memory

A flaw was found in PostgreSQL libpq. A server superuser can exploit a buffer overflow vulnerability in the PQfn function, which is used by client functions such as loexport, loread, lolseek64, and lotell64. This allows the superuser to send an arbitrarily large response, overwriting the client's...

Fixed in Apache Tomcat 9.0.121

Low: DoS in WebSocket chat example CVE-2026-66299 The WebSocket chat example provided an unbounded buffer for undelivered messages. A maliciously slow client could cause the buffer to grow continuously, eventually leading to an memory exhaustion and failure of the Tomcat process. This was fixed...

CVE-2026-62433

The CVE-2026-62433 issue relates to the Xen DM_OP handling path. Connected advisories document insufficient buffer checks in DM_OP hypercalls, allowing operations to proceed without validating the caller-supplied buffer count. This can enable reading of Xen stack contents and potentially leak dat...

CVE-2026-62424

CVE-2026-62424 affects the libfsimage iso9660 driver (Rock Ridge NM record processing). Attacker-controlled on-disk fields derive several lengths without validation, with potential underflow in System Use/Rock Ridge length handling, and specifically NM record processing may rely on a good entry l...

CVE-2026-42494

The CVE-2026-42494 issue affects the libfsimage iso9660 driver where on-disk fields controlled by an attacker are used to derive several lengths without validation. The directory loop assumes a valid record length, making it vulnerable to malformed directory records. Additional problems include p...
