Detailsinfo

A vulnerability was found in Qualcomm Snapdragon Mobile, Snapdragon Wear and Small Cell SoC (Chip Software). It has been classified as critical. Affected is an unknown code block of the component Camera Module. The manipulation with an unknown input leads to a integer overflow vulnerability. CWE is classifying the issue as CWE-190. The product performs a calculation that can produce an integer overflow or wraparound, when the logic assumes that the resulting value will always be larger than the original value. This can introduce other weaknesses when the calculation is used for resource management or execution control. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

Lack of check of buffer length before copying can lead to buffer overflow in camera module in Small Cell SoC, Snapdragon Mobile, Snapdragon Wear in FSM9055, FSM9955, IPQ4019, IPQ8064, MDM9206, MDM9607, MDM9640, MDM9650, MSM8909W, MSM8996AU, QCA9531, QCA9558, QCA9563, QCA9880, QCA9886, QCA9980, SD 210/SD 212/SD 205, SD 425, SD 427, SD 430, SD 435, SD 450, SD 615/16/SD 415, SD 625, SD 650/52, SD 800, SD 810, SD 820, SD 835, SDM630, SDM636, SDM660, SDX20, Snapdragon_High_Med_2016.

The weakness was disclosed 05/06/2019. This vulnerability is traded as CVE-2017-18279 since 05/18/2018. The exploitability is told to be easy. The attack needs to be approached locally.
