Description Tomas Hoger 2008-07-25 05:14:46 EDT
Common Vulnerabilities and Exposures assigned an identifier CVE-2008-3294 to the following vulnerability:

src/configure.in in Vim 5.0 through 7.1, when used for a build with
Python support, does not ensure that the Makefile-conf temporary file
has the intended ownership and permissions, which allows local users
to execute arbitrary code by writing to this file during a time window
associated with a race condition.

Comment 1 Tomas Hoger 2008-07-25 05:24:51 EDT
This issue can only be exploited during the package build and it does not affect
users of pre-built packages distributed with Red Hat Enterprise Linux or Fedora.
Therefore, we do not plan to backport a fix for this issue to already released
version of Red Hat Enterprise Linux.

Additionally, this issue requires an attacker to win a race against build
process, with very short time window for successful attack, giving an attacker a
low chance of success.
