Current Description

In Scanner::LiteralBuffer::NewCapacity of scanner.cc, there is a possible out of bounds write due to an integer overflow. This could lead to remote code execution if an attacker can supply a malicious PAC file, with no additional execution privileges needed. User interaction is not needed for exploitation.Product: AndroidVersions: Android-11 Android-8.1 Android-9 Android-10Android ID: A-168041375
