SB2015041901 - Permissions, Privileges, and Access Controls in Novell Opensuse

Description

This security bulletin contains information about 1 security vulnerability.

1) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2015-3335)

The vulnerability allows a remote non-authenticated attacker to read and manipulate data.

The NaClSandbox::InitializeLayerTwoSandbox function in components/nacl/loader/sandbox_linux/nacl_sandbox_linux.cc in Google Chrome before 42.0.2311.90 does not have RLIMIT_AS and RLIMIT_DATA limits for Native Client (aka NaCl) processes, which might make it easier for remote attackers to conduct row-hammer attacks or have unspecified other impact by leveraging the ability to run a crafted program in the NaCl sandbox.

Remediation

Install update from vendor's website.
