SUSE SLES11 Security Update : apache2 (SUSE-SU-2017:2907-1) (Optionsbleed)
Critical Nessus Plugin ID 104270
Synopsis
The remote SUSE host is missing one or more security updates.
Description
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)
