NASL family Ubuntu Local Security Checks NASL id UBUNTU_USN-4113-1.NASL description Stefan Eissing discovered that the HTTP/2 implementation in Apache did not properly handle upgrade requests from HTTP/1.1 to HTTP/2 in some situations. A remote attacker could use this to cause a denial of service (daemon crash). This issue only affected Ubuntu 18.04 LTS and Ubuntu 19.04. (CVE-2019-0197) Craig Young discovered that a memory overwrite error existed in Apache when performing HTTP/2 very early pushes in some situations. A remote attacker could use this to cause a denial of service (daemon crash). This issue only affected Ubuntu 18.04 LTS and Ubuntu 19.04. (CVE-2019-10081) Craig Young discovered that a read-after-free error existed in the HTTP/2 implementation in Apache during connection shutdown. A remote attacker could use this to possibly cause a denial of service (daemon crash) or possibly expose sensitive information. This issue only affected Ubuntu 18.04 LTS and Ubuntu 19.04. (CVE-2019-10082) Matei Badanoiu discovered that the mod_proxy component of Apache did not properly filter URLs when reporting errors in some configurations. A remote attacker could possibly use this issue to conduct cross-site scripting (XSS) attacks. (CVE-2019-10092) Daniel McCarney discovered that mod_remoteip component of Apache contained a stack buffer overflow when parsing headers from a trusted intermediary proxy in some situations. A remote attacker controlling a trusted proxy could use this to cause a denial of service or possibly execute arbitrary code. This issue only affected Ubuntu 19.04. (CVE-2019-10097) Yukitsugu Sasaki discovered that the mod_rewrite component in Apache was vulnerable to open redirects in some situations. A remote attacker could use this to possibly expose sensitive information or bypass intended restrictions. (CVE-2019-10098) Jonathan Looney discovered that the HTTP/2 implementation in Apache did not properly limit the amount of buffering for client connections in some situations. A remote attacker could use this to cause a denial of service (unresponsive daemon). This issue only affected Ubuntu 18.04 LTS and Ubuntu 19.04. (CVE-2019-9517). Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues. last seen 2020-06-01 modified 2020-06-02 plugin id 128412 published 2019-08-30 reporter Ubuntu Security Notice (C) 2019 Canonical, Inc. / NASL script (C) 2019 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/128412 title Ubuntu 16.04 LTS / 18.04 LTS / 19.04 : apache2 vulnerabilities (USN-4113-1) (Internal Data Buffering) code # # (C) Tenable Network Security, Inc. # # The descriptive text and package checks in this plugin were # extracted from Ubuntu Security Notice USN-4113-1.

Unfortunately, that update introduced a regression when proxying balancer manager connections in some configurations. This update fixes the problem. We apologize for the inconvenience. Original advisory details : Stefan Eissing discovered that the HTTP/2 implementation in Apache did not properly handle upgrade requests from HTTP/1.1 to HTTP/2 in some situations. A remote attacker could use this to cause a denial of service (daemon crash). This issue only affected Ubuntu 18.04 LTS and Ubuntu 19.04. (CVE-2019-0197) Craig Young discovered that a memory overwrite error existed in Apache when performing HTTP/2 very early pushes in some situations. A remote attacker could use this to cause a denial of service (daemon crash). This issue only affected Ubuntu 18.04 LTS and Ubuntu 19.04. (CVE-2019-10081) Craig Young discovered that a read-after-free error existed in the HTTP/2 implementation in Apache during connection shutdown. A remote attacker could use this to possibly cause a denial of service (daemon crash) or possibly expose sensitive information. This issue only affected Ubuntu 18.04 LTS and Ubuntu 19.04. (CVE-2019-10082) Matei Badanoiu discovered that the mod_proxy component of Apache did not properly filter URLs when reporting errors in some configurations. A remote attacker could possibly use this issue to conduct cross-site scripting (XSS) attacks. (CVE-2019-10092) Daniel McCarney discovered that mod_remoteip component of Apache contained a stack buffer overflow when parsing headers from a trusted intermediary proxy in some situations. A remote attacker controlling a trusted proxy could use this to cause a denial of service or possibly execute arbitrary code. This issue only affected Ubuntu 19.04. (CVE-2019-10097) Yukitsugu Sasaki discovered that the mod_rewrite component in Apache was vulnerable to open redirects in some situations. A remote attacker could use this to possibly expose sensitive information or bypass intended restrictions. (CVE-2019-10098) Jonathan Looney discovered that the HTTP/2 implementation in Apache did not properly limit the amount of buffering for client connections in some situations. A remote attacker could use this to cause a denial of service (unresponsive daemon). This issue only affected Ubuntu 18.04 LTS and Ubuntu 19.04. (CVE-2019-9517).
