CVE-2008-4190: The IPSEC livetest tool in Openswan 2.4.4 and earlier allows local users to overwrite arbitrary files and execute arbitrary code via a symlink attack on the (1) ipseclive.conn and (2) ipsec.olts.remote.log temporary files. To extend CVE description, this also affects 2.6.x versions (latest Fedora version is 2.6.16 and is affected by this problem). This is a bug, but no security issue whatsoever - ipsec livetest is not called by anything anywhere. It is an incomplete feature. - ipsec livetest contains the following code at the start of the script: echo "currently not used" exit OpenSwan version in all Fedora versions is based on 2.6.19, which does contain "echo & exit". Version shipped in Red Hat Enterprise Linux 5 is still based on 2.6.14, which does not have that, which might get changed in the future updates. Hence this still can be an issue if livetest is run manually. This issue has been addressed in following products: Red Hat Enterprise Linux 5 Via RHSA-2009:0402 https://rhn.redhat.com/errata/RHSA-2009-0402.html |
