- ========================================================================== Ubuntu Security Notice USN-5090-3 September 28, 2021
apache2 regression
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 21.04
- Ubuntu 20.04 LTS
- Ubuntu 18.04 LTS
Summary:
USN-5090-1 introduced a regression in Apache HTTP Server. One of the upstream fixes introduced a regression in UDS URIs. This update fixes the problem.
Original advisory details:
James Kettle discovered that the Apache HTTP Server HTTP/2 module incorrectly handled certain crafted methods. A remote attacker could possibly use this issue to perform request splitting or cache poisoning attacks. A remote attacker could possibly use this issue to cause the server to crash, resulting in a denial of service. (CVE-2021-34798) Li Zhi Xin discovered that the Apache mod_proxy_uwsgi module incorrectly handled certain request uri-paths. A remote attacker could possibly use this issue to cause the server to crash, resulting in a denial of service. This issue only affected Ubuntu 20.04 LTS and Ubuntu 21.04. If the server was configured with third-party modules, a remote attacker could use this issue to cause the server to crash, resulting in a denial of service, or possibly execute arbitrary code. (CVE-2021-39275) It was discovered that the Apache mod_proxy module incorrectly handled certain request uri-paths. A remote attacker could possibly use this issue to cause the server to forward requests to arbitrary origin servers. (CVE-2021-40438)
Update instructions:
The problem can be corrected by updating your system to the following package versions:
Ubuntu 21.04: apache2 2.4.46-4ubuntu1.3 apache2-bin 2.4.46-4ubuntu1.3
Ubuntu 20.04 LTS: apache2 2.4.41-4ubuntu3.6 apache2-bin 2.4.41-4ubuntu3.6
Ubuntu 18.04 LTS: apache2 2.4.29-1ubuntu4.18 apache2-bin 2.4.29-1ubuntu4.18
In general, a standard system update will make all the necessary changes. 7) - noarch, x86_64
Bug Fix(es):
- proxy rewrite to unix socket fails with CVE-2021-40438 fix (BZ#2022319)
Additional changes:
- To fix CVE-2022-29404, the default value for the "LimitRequestBody" directive in the Apache HTTP Server has been changed from 0 (unlimited) to 1 GiB.
On systems where the value of "LimitRequestBody" is not explicitly specified in an httpd configuration file, updating the httpd package sets "LimitRequestBody" to the default value of 1 GiB. As a consequence, if the total size of the HTTP request body exceeds this 1 GiB default limit, httpd returns the 413 Request Entity Too Large error code.
If the new default allowed size of an HTTP request message body is insufficient for your use case, update your httpd configuration files within the respective context (server, per-directory, per-file, or per-location) and set your preferred limit in bytes. For example, to set a new 2 GiB limit, use:
LimitRequestBody 2147483648
Systems already configured to use any explicit value for the "LimitRequestBody" directive are unaffected by this change.
For the oldstable distribution (buster), these problems have been fixed in version 2.4.38-3+deb10u6.
For the stable distribution (bullseye), these problems have been fixed in version 2.4.51-1~deb11u1.
We recommend that you upgrade your apache2 packages.
For the detailed security status of apache2 please refer to its security tracker page at: https://security-tracker.debian.org/tracker/apache2

One of the upstream\nfixes introduced a regression in UDS URIs. This update fixes the problem. \n\nOriginal advisory details:\n\n James Kettle discovered that the Apache HTTP Server HTTP/2 module\n incorrectly handled certain crafted methods. A remote attacker could\n possibly use this issue to perform request splitting or cache poisoning\n attacks. A remote attacker could possibly use this issue to\n cause the server to crash, resulting in a denial of service. \n (CVE-2021-34798)\n Li Zhi Xin discovered that the Apache mod_proxy_uwsgi module incorrectly\n handled certain request uri-paths. A remote attacker could possibly use\n this issue to cause the server to crash, resulting in a denial of service. \n This issue only affected Ubuntu 20.04 LTS and Ubuntu 21.04. If the server was configured with third-party modules, a remote\n attacker could use this issue to cause the server to crash, resulting in a\n denial of service, or possibly execute arbitrary code. (CVE-2021-39275)\n It was discovered that the Apache mod_proxy module incorrectly handled\n certain request uri-paths. A remote attacker could possibly use this issue\n to cause the server to forward requests to arbitrary origin servers. \n (CVE-2021-40438)\n\nUpdate instructions:\n\nThe problem can be corrected by updating your system to the following\npackage versions:\n\nUbuntu 21.04:\n apache2 2.4.46-4ubuntu1.3\n apache2-bin 2.4.46-4ubuntu1.3\n\nUbuntu 20.04 LTS:\n apache2 2.4.41-4ubuntu3.6\n apache2-bin 2.4.41-4ubuntu3.6\n\nUbuntu 18.04 LTS:\n apache2 2.4.29-1ubuntu4.18\n apache2-bin 2.4.29-1ubuntu4.18\n\nIn general, a standard system update will make all the necessary changes. 7) - noarch, x86_64\n\n3. \n\nBug Fix(es):\n\n* proxy rewrite to unix socket fails with CVE-2021-40438 fix (BZ#2022319)\n\nAdditional changes:\n\n* To fix CVE-2022-29404, the default value for the \"LimitRequestBody\"\ndirective in the Apache HTTP Server has been changed from 0 (unlimited) to\n1 GiB. \n\nOn systems where the value of \"LimitRequestBody\" is not explicitly\nspecified in an httpd configuration file, updating the httpd package sets\n\"LimitRequestBody\" to the default value of 1 GiB. As a consequence, if the\ntotal size of the HTTP request body exceeds this 1 GiB default limit, httpd\nreturns the 413 Request Entity Too Large error code. \n\nIf the new default allowed size of an HTTP request message body is\ninsufficient for your use case, update your httpd configuration files\nwithin the respective context (server, per-directory, per-file, or\nper-location) and set your preferred limit in bytes. For example, to set a\nnew 2 GiB limit, use:\n\nLimitRequestBody 2147483648\n\nSystems already configured to use any explicit value for the\n\"LimitRequestBody\" directive are unaffected by this change. \n\nFor the oldstable distribution (buster), these problems have been fixed\nin version 2.4.38-3+deb10u6. \n\nFor the stable distribution (bullseye), these problems have been fixed in\nversion 2.4.51-1~deb11u1. \n\nWe recommend that you upgrade your apache2 packages. \n\nFor the detailed security status of apache2 please refer to\nits security tracker page at:\nhttps://security-tracker.debian.org/tracker/apache2\n\nFurther information about Debian Security Advisories, how to apply\nthese updates to your system and frequently asked questions can be\nfound at: https://www.debian.org/security/\n\nMailing list: debian-security-announce@lists.debian.org\n-----BEGIN PGP SIGNATURE-----\n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\nA4CTIoYpK1WnsykAE8M4XFrnOW3lrtse6T8N/dTVMuodElAEhc0=\n=/At6\n-----END PGP SIGNATURE-----\n. - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -\nGentoo Linux Security Advisory GLSA 202208-20\n- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -\n https://security.gentoo.org/\n- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -\n\n Severity: High\n Title: Apache HTTPD: Multiple Vulnerabilities\n Date: August 14, 2022\n Bugs: #813429, #816399, #816864, #829722, #835131, #850622\n ID: 202208-20\n\n- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -\n\nSynopsis\n=======\nMultiple vulnerabilities have been discovered in Apache Webserver, the\nworst of which could result in remote code execution.
