Multiple buffer overflows in a certain ActiveX control in CryptoX.dll 2.0 and earlier in the Ultra Crypto Component allow remote attackers to execute arbitrary code via (1) a long string in the first argument to the AcquireContext method or (2) an unspecified vector to the DeleteContext method.
The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.
