high Nessus Plugin ID 198456

Synopsis

The remote Red Hat 4 host is affected by multiple vulnerabilities that will not be patched.

Description

The remote Redhat Enterprise Linux 4 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.

 - exim: local root privilege escalation for configurations with perl_startup (CVE-2016-1531)

 - The open_log function in log.c in Exim 4.72 and earlier does not check the return value from (1) setuid or (2) setgid system calls, which allows local users to append log data to arbitrary files via a symlink attack. (CVE-2011-0017)

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.
