It was discovered that Exim incorrectly handled certain return values when
handling logging. An attacker that obtained privileges of the 'Debian-exim'
user could use this flaw to obtain root privileges. (CVE-2011-0017)

Dan Rosenberg discovered that Exim incorrectly handled writable sticky-bit
mail directories. If Exim were configured in this manner, a local user
could use this flaw to cause a denial of service or possibly gain
privileges. This issue only applied to Ubuntu 6.06 LTS, 8.04 LTS, 9.10,
and 10.04 LTS. (CVE-2010-2023)

Dan Rosenberg discovered that Exim incorrectly handled MBX locking. If
Exim were configured in this manner, a local user could use this flaw to
cause a denial of service or possibly gain privileges. This issue only
applied to Ubuntu 6.06 LTS, 8.04 LTS, 9.10, and 10.04 LTS. (CVE-2010-2024)");
