CVE-2015-7211

Name of the Vulnerable Software and Affected Versions Mozilla Firefox versions prior to 43.0

Description The issue is related to errors in handling the "#" character in URI data, which can be exploited by a remote attacker to spoof websites. The estimated number of potentially affected devices and details about real-world incidents are not specified. Technical details about exploitation include mishandling of the # character in a data: URI, allowing remote attackers to spoof web sites via unspecified vectors.

Recommendations For versions prior to 43.0, update to version 43.0 or later to resolve the issue. As a temporary workaround, consider restricting the use of data: URI until a patch is available. Avoid using the # character in data: URI schemes to minimize the risk of exploitation.
