RHEL 7 : httpd (Unpatched Vulnerability)

critical Nessus Plugin ID 198675

Synopsis

The remote Red Hat 7 host is affected by multiple vulnerabilities that will not be patched.

Description

The remote Redhat Enterprise Linux 7 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

 - firefox: Possible integer overflow to fix inside XML_Parse in Expat (CVE-2016-9063)

 - mod_lua.c in the mod_lua module in the Apache HTTP Server 2.3.x and 2.4.x through 2.4.10 does not support an httpd configuration in which the same Lua authorization provider is used with different arguments within different contexts, which allows remote attackers to bypass intended access restrictions in opportunistic circumstances by leveraging multiple Require directives, as demonstrated by a configuration that specifies authorization for one group to access a certain directory, and authorization for a second group to access a second directory. (CVE-2014-8109)

 - Apache Portable Runtime Utility (APR-util) 1.6.0 and prior fail to validate the integrity of SDBM database files used by apr_sdbm*() functions, resulting in a possible out of bound read access. A local user with write access to the database can make a program or process using these functions crash, and cause a denial of service. (CVE-2017-12618)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

Solution

The vendor has acknowledged the vulnerabilities but no solution has been provided. Refer to the vendor for remediation guidance.
