Description:
Tim Rees has discovered a security issue in TrueCrypt, which can be exploited by malicious, local users to cause a DoS (Denial of Service) or gain escalated privileges.

The security issue is caused if the "truecrypt" binary is installed setuid root. This can be exploited to cause a DoS or gain escalated privileges by e.g. mounting a malicious TrueCrypt disk into /usr/bin or another user's home directory.

Successful exploitation requires that TrueCrypt is installed setuid root (not default setting).

The security issue is confirmed in version 4.3. Other versions may also be affected.
