Security Bulletin: Buffer overflow in V8
More support for: Rational Application Developer for WebSphere Software
Software version: 9.1, 188.8.131.52, 9.1.1, 184.108.40.206, 220.127.116.11, 9.5, 18.104.22.168, 22.214.171.124

Reference #: 1987182
Modified date: 2016-07-18
Under certain conditions, V8 may improperly expand memory allocations in the
`Zone::New` function. This could potentially be used to cause a Denial of
Service via buffer overflow or as a trigger for a remote code execution.
DESCRIPTION: Google Chrome is vulnerable to a buffer overflow, caused by an
error in V8. By persuading a victim to visit a specially-crafted Web site, a
remote attacker could overflow a buffer and execute arbitrary code on the
system or cause the application to crash.
