Untrusted search path vulnerability in Truecrypt 4.1, when running suid root on Linux, allows local users to execute arbitrary commands and gain privileges via a modified PATH environment variable that references a malicious mount command.

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.

TrueCrypt 5.0 stores pre-boot authentication passwords in the BIOS Keyboard buffer and does not clear this buffer before and after use, which allows local users to obtain sensitive information by reading the physical memory locations associated with this buffer. NOTE: the researcher mentions a response from the vendor denying the vulnerability.
