Alpine: multiple apache2 packages: security update to 2.4.26-r0

critical Tenable Cloud Security Plugin ID 423646

Description

There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

- In Apache httpd 2.2.x before 2.2.33 and 2.4.x before 2.4.26, use of the ap_get_basic_auth_pw() by third-
party modules outside of the authentication phase may lead to authentication requirements being bypassed.
(CVE-2017-3167)

- In Apache httpd 2.2.x before 2.2.33 and 2.4.x before 2.4.26, mod_ssl may dereference a NULL pointer when
third-party modules call ap_hook_process_connection() during an HTTP request to an HTTPS port.
(CVE-2017-3169)

- A maliciously constructed HTTP/2 request could cause mod_http2 in Apache HTTP Server 2.4.24, 2.4.25 to
dereference a NULL pointer and crash the server process. (CVE-2017-7659)

- The HTTP strict parsing changes added in Apache httpd 2.2.32 and 2.4.24 introduced a bug in token list
parsing, which allows ap_find_token() to search past the end of its input string. By maliciously crafting
a sequence of request headers, an attacker may be able to cause a segmentation fault, or to force
ap_find_token() to return an incorrect value. (CVE-2017-7668)

- In Apache httpd 2.2.x before 2.2.33 and 2.4.x before 2.4.26, mod_mime can read one byte past the end of a
buffer when sending a malicious Content-Type response header. (CVE-2017-7679)
