CVE-2024-34161 Details
Description
When NGINX Plus or NGINX OSS are configured to use the HTTP/3 QUIC module and the network infrastructure supports a Maximum Transmission Unit (MTU) of 4096 or greater without fragmentation, undisclosed QUIC packets can cause NGINX worker processes to leak previously freed memory.
A memory leak vulnerability has been identified in NGINX Plus and NGINX Open Source when the HTTP/3 QUIC module is enabled. This issue occurs on systems with a Maximum Transmission Unit (MTU) of 4096 bytes or greater, where undisclosed QUIC packets can cause NGINX worker processes to leak previously freed memory. The vulnerability affects NGINX versions 1.25.0 through 1.26.0, and is present in NGINX Plus by default, while in NGINX Open Source it requires the HTTP/3 QUIC module to be manually enabled.
Users can upgrade to NGINX versions 1.27.0 or 1.26.1 to address this vulnerability. For NGINX Plus users, the update is available in version R32.
