Security Bulletin

This security bulletin contains one low risk vulnerability.

1) Input validation error

EUVDB-ID: #VU17105

Risk: Low

CVSSv3.1: 4.9 [CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:L/A:L/E:U/RL:O/RC:C]

CVE-ID: CVE-2016-10739

CWE-ID: CWE-20 - Improper input validation

Exploit availability: No

Description

The vulnerability allows a remote attacker to bypass certain security restrictions.

The vulnerability exists due to the getaddrinfo() function accepts an IPv4 address followed by whitespace and arbitrary characters and treats his input as a correct IPv4 address. Software that accepts input from the getaddrinfo() function may incorrectly assume that the function return IPv4 address only. As a result, a remote attacker can inject arbitrary data into the IPv4 address and change application's behavior that relies on getaddrinfo() output (e.g., inject HTTP headers or other potentially dangerous strings).

Mitigation

Update the affected package glibc to the latest version.
