Description: This security update resolves a privately reported vulnerability
in Microsoft Windows. The vulnerability could allow information disclosure if
a user browses to a website containing a specially crafted JPEG XR (.JXR)
image. This vulnerability would not allow an attacker to execute code or to
elevate their user rights directly, but it could be used to obtain information
that could be used to try to further compromise the affected system.

Vulnerability Information
JPEG XR Parser Information Disclosure Vulnerability - CVE-2015-0076
An information disclosure vulnerability exists when Windows fails to properly
handle uninitialized memory when parsing certain, specially crafted JPEG XR
(.JXR) image format files. The vulnerability could allow information
disclosure if an attacker runs a specially crafted application on an affected
system.
To exploit the vulnerability, an attacker could host a specially crafted
website (or leverage a compromised website or one that accepts or hosts
user-provided content or advertisements) and then convince a user to visit the
website. In all cases, however, an attacker would have no way to force users
to visit a website. A user would have to be convinced to do so, typically by
way of a link in an email or Instant Messenger message that directs the user
to the attacker's website. It could also be possible to display specially
crafted web content through banner advertisements or other methods capable of
delivering web content to affected systems.
An attacker who successfully exploited this vulnerability could potentially
read data that was not intended to be disclosed. Note that this vulnerability
would not allow an attacker to execute code or to elevate their user rights
directly, but it could be used to obtain information that could be used to try
to further compromise the affected system. The update addresses the
vulnerability by correcting how Windows processes JPEG XR (.JXR) image format
files.
Microsoft received information about this vulnerability through coordinated
vulnerability disclosure. When this security bulletin was originally issued
Microsoft had not received any information to indicate that this vulnerability
had been publicly used to attack customers.
