Description

Opera for Linux, FreeBSD, and Solaris has a flaw in the createPattern function thatleaves old data that was in the memory before Opera allocated itin the new pattern. The pattern can be read and analyzed byJavaScript, so an attacker can get random samples of the user'smemory, which may contain data.
