{"id":"AZL-92385","summary":"CVE-2026-49855 affecting package python-tornado 6.3.3-11","details":"Tornado is a Python web framework and asynchronous networking library. Prior to 6.5.6, Tornado gzip decompression routines processed limited-size chunks but did not enforce an overall limit on accumulated decompressed chunks, allowing a malicious server accessed by SimpleAsyncHTTPClient or an HTTPServer configured with decompress_request=True to consume effectively unlimited memory. This issue is fixed in version 6.5.6.","modified":"2026-08-30T05:24:52Z","published":"2026-07-14T21:17:02Z","upstream":["CVE-2026-49855"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-49855"}],"affected":[{"package":{"name":"python-tornado","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/python-tornado"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"6.3.3-11"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-92385.json"}}],"schema_version":"1.9.0"}
