[ASA-201707-15] apache: multiple issues
Arch Linux Security Advisory ASA-201707-15 ========================================== Severity: Critical Date : 2017-07-14 CVE-ID : CVE-2017-9788 CVE-2017-9789 Package : apache Type : multiple issues Remote : Yes Link : https://security.archlinux.org/AVG-350 Summary ======= The package apache before version 2.4.27-1 is vulnerable to multiple issues including arbitrary code execution and information disclosure. Resolution ========== Upgrade to 2.4.27-1. # pacman -Syu "apache>=2.4.27-1" The problems have been fixed upstream in version 2.4.27. Workaround ========== None. Description =========== - CVE-2017-9788 (information disclosure) A security issue has been found in apache's mod_auth_digest <= 2.4.26, leading to information disclosure or denial of service. 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. - CVE-2017-9789 (arbitrary code execution) A security issue has been found in apache's mod_http2 <= 2.4.26. When under stress, closing many connections, the HTTP/2 handling code would sometimes access memory after it has been freed, resulting in potentially erratic behaviour. Impact ====== A remote attacker could access sensitive information if mod_auth_digest is enabled, or be able to execute arbitrary code on the affected host if mod_http2 is enabled.
