CVE-2017-14910

Vulnerability

Qualcomm Snapdragon chipsets including MDM9206, MDM9607, MDM9650, S820A, S820Am, SD 210/SD 212/SD 205, SD 410/12, SD 425, SD 430, SD 615/16/SD 415, SD 617, SD 625, SD 650/52, SD 820, SD 835, and SD 845 contain a buffer overread vulnerability. The issue occurs when an input file lacks newline characters, leading to a read beyond the allocated buffer. The affected components include automotive, IoT, and mobile platforms. [1]

Exploitation

An attacker can trigger the buffer overread by providing a specially crafted input file that contains no newline characters. The attacker must have the ability to supply this input to the vulnerable software module. The exact attack vector (e.g., local access, remote delivery) is not detailed but likely requires user interaction or a malicious application. [1]

Impact

Successful exploitation results in a buffer overread, which may allow an attacker to read out-of-bounds memory. This could lead to disclosure of sensitive information from the device's memory. The vulnerability does not directly enable arbitrary code execution or privilege escalation according to available information. [1]

Mitigation

The issue was fixed in the Android Security Bulletin dated February 2018, with security patch level 2018-02-05 or later addressing the vulnerability. Qualcomm and Android partners have released source code patches. Users should update their devices to the latest security patch level. No specific workarounds are documented. [1]
