The Windows driver used by projects derived from Truecrypt 7 (verified in Veracrypt and CipherShed) are vulnerable to a local elevation of privilege attack by abusing the drive letter symbolic link creation facilities to remap the main system drive. With the system drive remapped it's trivial to get a new process running under the local system account.
bd1e8ffc132fe9efac975acbab5528bd06a2731798e1f40805ddc035d825f919The proof of concept works by triggering a wild copy in order to demonstrate the crash. But other side-effects are possible such as decrementing the refcount of an out-of-bounds index.

32f8d2576cdd393f19c2a9cdbb6d3476d8fda0611004641c02e347365ebea2aeThe "transient array" specified in the "Type 2 Charstring format" specs but also available in Type1 fonts (originally for the purpose of facilitating Multiple Master fonts) is allocated dynamically only if the CoolType interpreter encounters an instruction which requires the presence of the array, such as "get" or "store". While allocating the array, however, the routine does not automatically clear the contents of the newly created buffer.
6ace69fba4e02dc5c9eedf369a1611909bcd055bd1c38c7a835323a1176ce061There is an error in the PCRE engine version used in Flash that allows the execution of arbitrary PCRE bytecode, with potential for memory corruption and remote code execution.
f100f0c5cc96a2a407b46491520f1bce43ba7ca526f4e6c69f5887bf768c2ecaThe Type1/CFF CharString interpreter code in the Adobe Type Manager Font Driver (ATMFD.DLL) Windows kernel module does not perform nearly any verification that the operand stack is large enough to contain the required instruction operands, which can lead to up to "off-by-three" overreads and overwrites on the interpreter function stack.
51ba13f671a701f0476a89dfbec32f4088b01330862ec09c0a793c9e3d8643a0The system call NtPowerInformation performs a check that the caller is an administrator before performing some specific power functions. The check is done in the PopUserIsAdmin function. On Windows 7 this check is bypassable because the SeTokenIsAdmin function doesn't take into account the impersonation level of the token and the rest of the code also doesn't take it into account.
