Summary

IBM Security SiteProtector System has addressed the following vulnerabilities
in Apache HTTP Server.

Vulnerability Details

CVEID: CVE-2017-7679
DESCRIPTION: Apache HTTPD could allow a remote attacker to obtain sensitive
information, caused by a buffer overread in mod_mime. By sending a specially
crafted Content-Type response header, a remote attacker could exploit this
vulnerability to read one byte past the end of a buffer.
CVSS Base Score: 5.3
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/
127420 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N)

CVEID: CVE-2017-7668
DESCRIPTION: Apache HTTPD is vulnerable to a denial of service, caused by a
buffer overread in the ap_find_token() function. By sending a specially crafted
sequence of request headers, a remote attacker could exploit this vulnerability
to cause a segmentation fault.
CVSS Base Score: 5.3
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/
127419 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L)

CVEID: CVE-2017-3167
DESCRIPTION: Apache HTTPD could allow a remote attacker to bypass security
restrictions, caused by the use of the ap_get_basic_auth_pw() function by
third-party modules outside of the authentication phase. A remote attacker
could exploit this vulnerability to bypass authentication requirements.
CVSS Base Score: 5.3
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/
127416 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N)
