Insight
It was discovered that Emacs did not account for precision when formatting integers. If a user were tricked into opening a specially crafted file, an attacker could cause a denial of service or possibly other unspecified actions. This issue does not affect Ubuntu 8.04. (CVE-2007-6109) Steve Grubb discovered that the vcdiff script as included in Emacs created temporary files in an insecure way when used with SCCS. Local users could exploit a race condition to create or overwrite files with the privileges of the user invoking the program. (CVE-2008-1694)
