TrueCrypt execvp() PATH privilege escalation
|truecrypt-execvp-gain-privileges (26191)||Medium Risk|
TrueCrypt could allow a local attacker to gain elevated privileges caused by an error when processing path environments. When path environments are processed before the execvp() function is called, a local attacker could exploit this vulnerability to execute arbitrary commands with elevated privileges.
Upgrade to the latest version of TrueCrypt (4.2 or later), available from the TrueCrypt Web site. See References.
