Integer overflow vulnerability in LINE(Android) from 4.4.0 to the version before 9.15.1 allows remote attackers to cause a denial of service (DoS) condition or execute arbitrary code via a specially crafted image.

An issue was discovered in the LINE jp.naver.line application 8.8.1 for Android. The Passcode feature allows authentication bypass via runtime manipulation that forces a certain method's return value to true. In other words, an attacker could authenticate with an arbitrary passcode. NOTE: the vendor indicates that this is not an attack of interest within the context of their threat model, which excludes Android devices on which rooting has occurred
