Details

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)
