Buffer overflow in Node.js

1) Buffer overflow

EUVDB-ID: #VU41349

Risk: Medium

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

CVE-ID: CVE-2014-5256

CWE-ID: CWE-119 - Memory corruption

Exploit availability: No

Description

The vulnerability allows a remote non-authenticated attacker to perform service disruption.

Node.js 0.8 before 0.8.28 and 0.10 before 0.10.30 does not consider the possibility of recursive processing that triggers V8 garbage collection in conjunction with a V8 interrupt, which allows remote attackers to cause a denial of service (memory corruption and application crash) via deep JSON objects whose parsing lets this interrupt mask an overflow of the program stack.

Mitigation

Install update from vendor's website.

Vulnerable software versions

Node.js: 0.8.0 - 0.10.29
