CyberRota Analysis
AI-GeneratedAn integer overflow vulnerability in the packet buffer growth logic of PgBouncer versions up to 1.25.2 allows unauthenticated remote attackers to exploit this flaw, leading to a denial of service condition. By sending sufficiently large input, the overflow prevents the buffer growth loop from terminating, causing CPU saturation and stalling all pooled connections until the process is terminated. Organizations using PgBouncer should prioritize patching this vulnerability to mitigate potential service disruptions.
Original NVD Description
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 clients from a single process, this saturates a CPU core and stalls every pooled connection until the process is killed. Both unauthenticated and authenticated code paths can reach the overflow.
