TITLE

Snapdragon Mobile Buffer error vulnerability

Trust: 0.8

sources: JVNDB: JVNDB-2018-011437

DESCRIPTION

When the buffer length passed is very large in WLAN, bounds check could be bypassed leading to potential buffer overwrite in Snapdragon Mobile in version SD 835, SD 845, SD 850, SDA660. Snapdragon Mobile Contains a buffer error vulnerability.Information is obtained, information is altered, and service operation is disrupted (DoS) There is a possibility of being put into a state. Qualcomm Closed-Source Components are prone to multiple unspecified vulnerabilities. An attacker can exploit these issues to perform unauthorized actions. This may aid in further attacks. These issues are being tracked by Android Bug IDs A-120487384, A-117119000, A-117118976, A-117118295, A-117119172, A-122473270, A-109678120, A-111093019, A-111092813, A-111089816, A-111092945, A-111092919, A-111091938, A-111093762, A-111093242, A-111090373, A-111092814, A-111093763, A-111093243, A-111089817, A-111092400, A-111090534, A-111091378, A-111092946, A-111093022, A-111093244, A-111092888, A-111093280, A-111092401, A-111093259, A-111090535, A-112279580, A-112279127, A-119049704, A-119052960, A-114042276, A-117118499, A-117119174, A-117119152, A-117118789, A-122472377, A-120483842, A-122472139 and A-122473145. Qualcomm SD 835, etc. are the central processing unit (CPU) products of Qualcomm (Qualcomm) for mobile devices. WLAN is one of the wireless local area network components. A buffer overflow vulnerability exists in WLAN in several Qualcomm Snapdragon products. A local attacker could exploit this vulnerability to execute arbitrary code or cause a denial of service. The following products (for mobile devices) are affected: Qualcomm Snapdragon Mobile SD 835; SD 845; SD 850; SDA660
