ImageIO in Apple Safari before 4.0.5 and iTunes before 9.1 on Windows does not ensure that memory access is associated with initialized memory, which allows remote attackers to obtain potentially sensitive information from process memory via a crafted BMP image.
Available for: Windows 7, Vista, XP
Impact: Visiting a maliciously crafted website may result in sending
data from Safari's memory to the website
Description: An uninitialized memory access issue exists in
ImageIO's handling of BMP images. Visiting a maliciously crafted
website may result in sending data from Safari's memory to the
website. This issue is addressed through improved memory handling and
additional validation of BMP images. Credit to Matthew 'j00ru'
