Synopsis

The remote SUSE host is missing one or more security updates.

Description

This update for apache2 fixes several issues. These security issues were fixed :

- CVE-2017-9798: Prevent use-after-free use of memory that allowed for an information leak via OPTIONS (bsc#1058058)

- CVE-2017-9788: Uninitialized memory reflection in mod_auth_digest could have lead to leakage of potentially confidential information, and a segfault in other cases resulting in DoS (bsc#1048576).

- 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).

- CVE-2017-3169: mod_ssl may dereferenced 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).

The update package also includes non-security fixes. See advisory for details.

Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
