A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.\n\nThe httpd packages provide the Apache HTTP Server, a powerful, efficient, and extensible web server.\n\nSecurity Fix(es) :\n\n* It was discovered that the httpd's mod_auth_digest module did not properly initialize memory before using it when processing certain headers related to digest authentication. A remote attacker could possibly use this flaw to disclose potentially sensitive information or cause httpd child process to crash by sending specially crafted requests to a server. (CVE-2017-9788)\n\n* It was discovered that the use of httpd's ap_get_basic_auth_pw() API function outside of the authentication phase could lead to authentication bypass. A remote attacker could possibly use this flaw to bypass required authentication if the API was used incorrectly by one of the modules used by httpd. (CVE-2017-3167)\n\n* A NULL pointer dereference flaw was found in the httpd's mod_ssl module. A remote attacker could use this flaw to cause an httpd child process to crash if another module used by httpd called a certain API function during the processing of an HTTPS request. (CVE-2017-3169)\n\n* A buffer over-read flaw was found in the httpd's mod_mime module. A user permitted to modify httpd's MIME configuration could use this flaw to cause httpd child process to crash. (CVE-2017-7679)\n\n* A use-after-free flaw was found in the way httpd handled invalid and previously unregistered HTTP methods specified in the Limit directive used in an .htaccess file. A remote attacker could possibly use this flaw to disclose portions of the server memory, or cause httpd child process to crash. (CVE-2017-9798)\n\nRed Hat would like to thank Hanno Bock for reporting CVE-2017-9798.", "published": "2017-11-14T00:00:00", "modified": "2019-10-24T00:00:00", "cvss": {"score": 7.5, "vector":

A Common Vulnerability Scoring System (CVSS) base\nscore, which gives a detailed severity rating, is available for each\nvulnerability from the CVE link(s) in the References section.\n\nThe httpd packages provide the Apache HTTP Server, a powerful,\nefficient, and extensible web server.\n\nSecurity Fix(es) :\n\n* It was discovered that the httpd's mod_auth_digest module did not\nproperly initialize memory before using it when processing certain\nheaders related to digest authentication. A remote attacker could\npossibly use this flaw to disclose potentially sensitive information\nor cause httpd child process to crash by sending specially crafted\nrequests to a server. (CVE-2017-9788)\n\n* It was discovered that the use of httpd's ap_get_basic_auth_pw() API\nfunction outside of the authentication phase could lead to\nauthentication bypass. A remote attacker could possibly use this flaw\nto bypass required authentication if the API was used incorrectly by\none of the modules used by httpd. (CVE-2017-3167)\n\n* A NULL pointer dereference flaw was found in the httpd's mod_ssl\nmodule. A remote attacker could use this flaw to cause an httpd child\nprocess to crash if another module used by httpd called a certain API\nfunction during the processing of an HTTPS request. (CVE-2017-3169)\n\n* A buffer over-read flaw was found in the httpd's mod_mime module. A\nuser permitted to modify httpd's MIME configuration could use this\nflaw to cause httpd child process to crash. (CVE-2017-7679)\n\n* A use-after-free flaw was found in the way httpd handled invalid and\npreviously unregistered HTTP methods specified in the Limit directive\nused in an .htaccess file. A remote attacker could possibly use this\nflaw to disclose portions of the server memory, or cause httpd child\nprocess to crash.

this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.\n\nThe httpd packages provide the Apache HTTP Server, a powerful, efficient, and extensible web server.\n\nSecurity Fix(es) :\n\n* It was discovered that the httpd's mod_auth_digest module did not properly initialize memory before using it when processing certain headers related to digest authentication. A remote attacker could possibly use this flaw to disclose potentially sensitive information or cause httpd child process to crash by sending specially crafted requests to a server. (CVE-2017-9788)\n\n* It was discovered that the use of httpd's ap_get_basic_auth_pw() API function outside of the authentication phase could lead to authentication bypass. A remote attacker could possibly use this flaw to bypass required authentication if the API was used incorrectly by one of the modules used by httpd. (CVE-2017-3167)\n\n* A NULL pointer dereference flaw was found in the httpd's mod_ssl module. A remote attacker could use this flaw to cause an httpd child process to crash if another module used by httpd called a certain API function during the processing of an HTTPS request. (CVE-2017-3169)\n\n* A buffer over-read flaw was found in the httpd's mod_mime module. A user permitted to modify httpd's MIME configuration could use this flaw to cause httpd child process to crash.

(CVE-2016-8743)\n\nap_get_basic_auth_pw() authentication bypass :\n\nIt was discovered that the use of httpd's ap_get_basic_auth_pw() API\nfunction outside of the authentication phase could lead to\nauthentication bypass. A remote attacker could possibly use this flaw\nto bypass required authentication if the API was used incorrectly by\none of the modules used by httpd. (CVE-2017-3167)\n\nmod_mime buffer overread :\n\nA buffer over-read flaw was found in the httpd's mod_mime module. A\nuser permitted to modify httpd's MIME configuration could use this\nflaw to cause httpd child process to crash. (CVE-2017-7679)\n\nmod_http2 NULL pointer dereference :\n\nA NULL pointer dereference flaw was found in the mod_http2 module of\nhttpd.
