Name of the Vulnerable Software and Affected Versions: Android for MSM (affected versions not specified) Firefox OS for MSM (affected versions not specified) QRD Android (affected versions not specified)

Description: The issue allows userspace to pass information elements (IEs) to the host driver. If multiple append commands are received, an integer variable storing the length can overflow. This overflow may lead to a heap buffer overflow when copying IE data.

Recommendations: For Android for MSM, update to a version that includes a fix for the integer overflow issue. For Firefox OS for MSM, update to a version that includes a fix for the integer overflow issue. For QRD Android, update to a version that includes a fix for the integer overflow issue. As a temporary workaround, consider restricting the use of append commands to minimize the risk of exploitation.
