CVSS 3.0
9.1 criticalCVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:HCVE-2017-9788
In Apache httpd before 2.2.34 and 2.4.x before 2.4.27, the value placeholder in [Proxy-]Authorization headers of type 'Digest' was not initialized or reset before or between successive key=value assignments by mod_auth_digest. Providing an initial key with no '=' assignment could reflect the stale value of uninitialized pool memory used by the prior request, leading to leakage of potentially confidential information, and a segfault in other cases resulting in denial of service.
