**According to the CVSS metric, user interaction is required (UI:R). What interaction would the user have to do?** Exploitation of the vulnerability requires that a user open a specially crafted file. * In an email attack scenario, an attacker could exploit the vulnerability by sending the specially crafted file to the user and convincing the user to open the file. * In a web-based attack scenario, an attacker could host a website (or leverage a compromised website that accepts or hosts user-provided content) containing a specially crafted file designed to exploit the vulnerability. An attacker would have no way to force users to visit the website. Instead, an attacker would have to convince users to click a link, typically by way of an enticement in an email or instant message, and then convince them to open the specially crafted file.

**What security feature is being bypassed?** An attacker with a machine-in-the-middle (MitM) position who successfully exploited this vulnerability could bypass the certificate validation performed when a targeted user connects to a trusted server.

**What type of information could be disclosed by this vulnerability?** The type of information that could be disclosed if an attacker successfully exploited this vulnerability is uninitialized memory.

**According to the CVSS metric, the attack complexity is high (AC:H). What does that mean for this vulnerability?** Successful exploitation of this vulnerability requires an attacker to win a race condition.

**According to the CVSS metric, user interaction is required (UI:R). What interaction would the user have to do?** The user would have to click on a specially crafted URL to be compromised by the attacker.

**What type of information could be disclosed by this vulnerability?** An attacker who successfully exploited this vulnerability could potentially read small portions of heap memory.

**What type of information could be disclosed by this vulnerability?** An attacker who successfully exploited this vulnerability could potentially read small portions of heap memory.

**What privileges could be gained by an attacker who successfully exploited this vulnerability?** An attacker who successfully exploited this vulnerability could gain SYSTEM privileges.
