Buffer overflow in pgpwded.sys in Symantec PGP Desktop 10.x and Encryption Desktop 10.3.0 before MP1 on Windows XP and Server 2003 allows local users to gain privileges via a crafted application.
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.
