BIT-PGBOUNCER-2026-6668 Integer overflow causes an infinite loop in packet buffer growth in PgBouncer

Integer overflow in the packet buffer growth logic in PgBouncer through 1.25.2 allows an unauthenticated remote attacker to cause a denial of service. Sufficiently large input makes the buffer size computation overflow, leaving the growth loop unable to terminate. Because PgBouncer serves all...

openssl: openssl: Denial of Service via excessive QUIC packet buffer retention

A flaw was found in OpenSSL. A remote attacker can cause a Denial of Service DoS by sending specially crafted network packets to a QUIC protocol endpoint. Because the QUIC stack retains memory in packet buffers until the receiving application reads the stream data, an attacker can manipulate data...
