CVE-2015-3863
HighSummary
Multiple integer overflows in the Blob class in keystore/keystore.cpp in Android before version 5.1.1 LMY48M allow attackers to execute arbitrary code and read arbitrary Keystore keys via an application that uses a crafted blob in an insert operation.
Risk Assessment
This vulnerability poses a risk of arbitrary code execution and unauthorized access to Keystore keys, potentially leading to serious data security breaches.
Recommendation
It is recommended to update Android to version 5.1.1 LMY48M or later to mitigate this vulnerability and reduce the risk of attacks.
