{"id":"UBUNTU-CVE-2024-52304","details":"aiohttp is an asynchronous HTTP client/server framework for asyncio and Python. Prior to version 3.10.11, the Python parser parses newlines in chunk extensions incorrectly which can lead to request smuggling vulnerabilities under certain conditions. If a pure Python version of aiohttp is installed (i.e. without the usual C extensions) or `AIOHTTP_NO_EXTENSIONS` is enabled, then an attacker may be able to execute a request smuggling attack to bypass certain firewalls or proxy protections. Version 3.10.11 fixes the issue.","modified":"2026-02-04T04:40:29.855824Z","published":"2024-11-18T21:15:00Z","related":["USN-7642-1"],"upstream":["CVE-2024-52304"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2024-52304"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2024-52304"},{"type":"REPORT","url":"https://github.com/aio-libs/aiohttp/security/advisories/GHSA-8495-4g3g-x7pr"},{"type":"REPORT","url":"https://github.com/aio-libs/aiohttp/commit/259edc369075de63e6f3a4eaade058c62af0df71"},{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-7642-1"}],"affected":[{"package":{"name":"python-aiohttp","ecosystem":"Ubuntu:Pro:18.04:LTS","purl":"pkg:deb/ubuntu/python-aiohttp@3.0.1-1ubuntu0.1~esm5?arch=source&distro=esm-apps/bionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.0.1-1ubuntu0.1~esm5"}]}],"versions":["2.2.3-1build1","2.2.3-2","2.3.6-1","3.0.1-1","3.0.1-1ubuntu0.1~esm1","3.0.1-1ubuntu0.1~esm4"],"ecosystem_specific":{"availability":"Available with Ubuntu Pro: https://ubuntu.com/pro","binaries":[{"binary_name":"python3-aiohttp","binary_version":"3.0.1-1ubuntu0.1~esm5"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2024/UBUNTU-CVE-2024-52304.json"}},{"package":{"name":"python-aiohttp","ecosystem":"Ubuntu:Pro:22.04:LTS","purl":"pkg:deb/ubuntu/python-aiohttp@3.8.1-4ubuntu0.2+esm1?arch=source&distro=esm-apps/jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.8.1-4ubuntu0.2+esm1"}]}],"versions":["3.7.4-1","3.7.4-1build2","3.8.1-3","3.8.1-4","3.8.1-4build1","3.8.1-4ubuntu0.2"],"ecosystem_specific":{"availability":"Available with Ubuntu Pro: https://ubuntu.com/pro","binaries":[{"binary_name":"python3-aiohttp","binary_version":"3.8.1-4ubuntu0.2+esm1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2024/UBUNTU-CVE-2024-52304.json"}},{"package":{"name":"python-aiohttp","ecosystem":"Ubuntu:Pro:24.04:LTS","purl":"pkg:deb/ubuntu/python-aiohttp@3.9.1-1ubuntu0.1+esm1?arch=source&distro=esm-apps/noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.9.1-1ubuntu0.1+esm1"}]}],"versions":["3.8.4-1","3.9.1-1","3.9.1-1build1","3.9.1-1ubuntu0.1"],"ecosystem_specific":{"availability":"Available with Ubuntu Pro: https://ubuntu.com/pro","binaries":[{"binary_name":"python3-aiohttp","binary_version":"3.9.1-1ubuntu0.1+esm1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2024/UBUNTU-CVE-2024-52304.json"}}],"schema_version":"1.7.3","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N"},{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N"},{"type":"Ubuntu","score":"medium"}]}
