tornado: Tornado: Denial of Service via uncontrolled gzip decompression memory consumption

A flaw was found in Tornado, a Python web framework and asynchronous networking library. Its gzip decompression routines process data in limited-size chunks but do not enforce an overall limit on the total accumulated decompressed data. This vulnerability allows a malicious server to consume...

CVE-2026-53716

A flaw was found in Envoy Gateway. A remote attacker, by providing a specially crafted compressed WebAssembly Wasm payload through a tenant-controlled URL, can exploit a vulnerability where the system decompresses the gzip file without limiting the output size. This can lead to an uncontrolled...

AZL-105378 CVE-2026-103262 affecting package python-tornado 6.3.3-11

Tornado versions before 6.5.9 contain an unbounded memory accumulation vulnerability in CurlAsyncHTTPClient that allows remote attackers to cause denial of service by sending a compressed response. Attackers can send a gzip-encoded decompression bomb that accumulates in memory without size limits...
