TrueCrypt 4.3, when installed setuid root, allows local users to cause a denial of service (filesystem unavailability) or gain privileges by mounting a crafted TrueCrypt volume, as demonstrated using (1) /usr/bin or (2) another user's home directory, a different issue than CVE-2007-1589.
TrueCrypt before 4.3, when set-euid mode is used on Linux, allows local users to cause a denial of service (filesystem unavailability) by dismounting a volume mounted by a different user.
