RHEL 5 : kernel (Unpatched Vulnerability)

critical Nessus Plugin ID 199257


The remote Red Hat 5 host is affected by multiple vulnerabilities that will not be patched.


The remote Redhat Enterprise Linux 5 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.

- kernel: netfilter: use-after-free in tcpmss_mangle_packet function in net/netfilter/xt_TCPMSS.c (CVE-2017-18017)

- The ia64 subsystem in the Linux kernel before 2.6.26 allows local users to cause a denial of service (stack consumption and system crash) via a crafted application that leverages the mishandling of invalid Register Stack Engine (RSE) state. (CVE-2006-3635)

- drivers/media/video/videobuf-vmalloc.c in the Linux kernel before 2.6.24 does not initialize videobuf_mapping data structures, which allows local users to trigger an incorrect count value and videobuf leak via unspecified vectors, a different vulnerability than CVE-2010-5321. (CVE-2007-6761)

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


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