1) Buffer overflow

EUVDB-ID: #VU40787

Risk: Medium

CVSSv4.0: 2.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N/E:U/U:Green]

CVE-ID: CVE-2015-1252

CWE-ID: CWE-119 - Memory corruption

Exploit availability: No

Description

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

common/partial_circular_buffer.cc in Google Chrome before 43.0.2357.65 does not properly handle wraps, which allows remote attackers to bypass a sandbox protection mechanism or cause a denial of service (out-of-bounds write) via vectors that trigger a write operation with a large amount of data, related to the PartialCircularBuffer::Write and PartialCircularBuffer::DoWrite functions.

Mitigation

Install update from vendor's website.
