CVE-2023-39322 (GCVE-0-2023-39322)

Vulnerability from cvelistv5 – Published: 2023-09-08 16:13 – Updated: 2025-02-13 17:02
VLAI
Title
Memory exhaustion in QUIC connection handling in crypto/tls
Summary
QUIC connections do not set an upper bound on the amount of data buffered when reading post-handshake messages, allowing a malicious QUIC connection to cause unbounded memory growth. With fix, connections now consistently reject messages larger than 65KiB in size.
Severity
No CVSS data available.
