The Solaris pollset feature in the Event Port backend in poll/unix/port.c in the Apache Portable Runtime (APR) library before 1.3.9, as used in the Apache HTTP Server before 2.2.14 and other products, does not properly handle errors, which allows remote attackers to cause a denial of service (daemon hang) via unspecified HTTP requests, related to the prefork and event MPMs.

Security update for apache2
This update for apache2 fixes the following issues:
- Allow disabling SNI on proxy connections using 'SetEnv proxy-disable-sni 1' in the configuration files. (bsc#1052830)
- Allow ECDH again in mod_ssl, it had been incorrectly disabled with the 2.2.34 update. (bsc#1064561)
Following security issue has been fixed:
- CVE-2017-9798: A use-after-free in the OPTIONS command could be used by attackers to disclose memory of the apache server process, when htaccess uses incorrect Limit statement. (bsc#1058058)
Additionally, references to the following security issues, fixed by the previous version-update of apache2 to Apache HTTPD 2.2.34 have been added:
- CVE-2017-7668: The HTTP strict parsing introduced a bug in token list parsing, which allowed ap_find_token() to search past the end of its input string. By maliciously crafting a sequence of request headers, an attacker may have be able to cause a segmentation fault, or to force ap_find_token() to return an incorrect value. (bsc#1045061)
- CVE-2017-3169: mod_ssl may have de-referenced a NULL pointer when third-party modules call ap_hook_process_connection() during an HTTP request to an HTTPS port allowing for DoS. (bsc#1045062)
- CVE-2017-3167: Use of the ap_get_basic_auth_pw() by third-party modules outside of the authentication phase may have lead to authentication requirements being bypassed. (bsc#1045065)
- CVE-2017-7679: mod_mime could have read one byte past the end of a buffer when sending a malicious Content-Type response header. (bsc#1045060)
