Description Preview
CVE-2017-14878 affects Android for MSM, Firefox OS for MSM, QRD Android, and all Android releases from CAF using the Linux kernel. The vulnerability involves a length variable with a size of only 8 bits that is used to copy data. When this 8-bit length variable is exceeded, it can result in a denial of service condition. This improper input validation issue (CWE-20) was addressed in a security patch released by Qualcomm and included in the Android Security Bulletin of March 2018.
Overview
This vulnerability exists in Qualcomm's wireless components used in various Android devices. The core issue is that a length variable used for data copying operations is limited to 8 bits (maximum value of 255), but can receive values that exceed this limit. When larger values are provided, buffer overflow conditions can occur, leading to denial of service situations where the affected component or system becomes unresponsive or crashes. The vulnerability affects multiple Qualcomm-based Android systems and was categorized as an improper input validation issue (CWE-20).
Remediation
- Update affected devices to the security patch level of March 2018 or later, which includes the fix for this vulnerability.
- If you're a developer working with the affected code base, apply the patch referenced in the commit: 27f1c544d6737bcb3dc4bb114badcd47ce946a8b
- System administrators should ensure that all Qualcomm-based Android devices in their environment are updated with the latest security patches.
- If updates are not available for your device, consider limiting network connectivity or using the device in a restricted environment to reduce the risk of exploitation.
- Monitor system logs for unexpected crashes that might indicate exploitation attempts.
