Comment 2 Arvid Requate

Upstream Debian package version 2.2.22-13+deb7u9 fixes

* 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)
* 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)
* 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)
* mod_mime can read one byte past the end of a buffer when sending a malicious Content-Type response header. (CVE-2017-7679)

Comment 3 Arvid Requate

2017-08-07 15:47:59 CEST

2.2.22-13+deb7u10 fixes:

* 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. (CVE-2017-9788)


And 2.2.22-13+deb7u11 fixes a regression.

Comment 4 Arvid Requate

2017-10-30 14:55:22 CET

Upstream Debian package version 2.2.22-13+deb7u12 fixes:

* Apache httpd allows remote attackers to read secret data from process memory if the Limit directive can be set in a user's .htaccess file, or if httpd.conf has certain misconfigurations, aka Optionsbleed. The attacker sends an unauthenticated OPTIONS HTTP request when attempting to read secret data. This is a use-after-free issue and thus secret data is not always sent, and the specific data depends on many factors including configuration. Exploitation with .htaccess can be blocked with a patch to the ap_limit_section function in server/core.c. (CVE-2017-9798)
