racoon/gssapi.c in IPsec-Tools 0.8.2 allows remote attackers to cause a denial of service (NULL pointer dereference and IKE daemon crash) via a series of crafted UDP requests.

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.

  - ipsec-tools: Parsing and storing ISAKMP fragments in malicious order can exhaust resources     (CVE-2016-10396)

  - racoon/gssapi.c in IPsec-Tools 0.8.2 allows remote attackers to cause a denial of service (NULL pointer     dereference and IKE daemon crash) via a series of crafted UDP requests. (CVE-2015-4047)

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

Impact

When this vulnerability is exploited, the remote attacker may be able use crafted UDP requests to cause the racoon process to stop responding, resulting in a denial-of-service (DoS) attack.

ipsec-tools was updated to fix one security issue and a bug.

This security issue was fixed :

  - CVE-2015-4047: racoon/gssapi.c in ipsec-tools allowed     remote attackers to cause a denial of service (NULL     pointer dereference and IKE daemon crash) via a series     of crafted UDP requests (bsc#931989).

Due to a packaging error, the racoonf.conf config file was symlinked to /usr/share/doc/packages/ipsec-tools/examples/racoon/samples/racoon.con f on some processor platforms, edits might have happened only in this example file.

Before upgrading, please check if /etc/racoon/racoon.conf is a symlink to this example file and backup the content. (bsc#939810)
