{"id":"USN-7015-7","summary":"python2.7 regression","details":"USN-7015-4 fixed vulnerabilities in Python. It was discovered that the fix\nfor CVE-2023-27043 for python2.7 was incorrectly applied on Ubuntu 16.04\nLTS and Ubuntu 18.04 LTS. This update fixes the problem.\n\nWe apologize for the inconvenience.\n\nOriginal advisory details:\n\n It was discovered that the Python email module incorrectly parsed email\n addresses that contain special characters. A remote attacker could\n possibly use this issue to bypass certain protection mechanisms.\n (CVE-2023-27043)\n\n It was discovered that Python allowed excessive backtracking while parsing\n certain tarfile headers. A remote attacker could possibly use this issue\n to cause Python to consume resources, leading to a denial of service.\n (CVE-2024-6232)\n\n It was discovered that the Python email module incorrectly quoted newlines\n for email headers. A remote attacker could possibly use this issue to\n perform header injection. (CVE-2024-6923)\n\n It was discovered that the Python http.cookies module incorrectly handled\n parsing cookies that contained backslashes for quoted characters. A remote\n attacker could possibly use this issue to cause Python to consume\n resources, leading to a denial of service. (CVE-2024-7592)\n\n It was discovered that the Python zipfile module incorrectly handled\n certain malformed zip files. A remote attacker could possibly use this\n issue to cause Python to stop responding, resulting in a denial of\n service.
