EUVDB-ID: #VU32797

Risk: Low

CVSSv3.1: 7.3 [CVSS:3.1/CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2012-2337

CWE-ID: CWE-264 - Permissions, Privileges, and Access Controls

Exploit availability: No

Description

The vulnerability allows a local non-authenticated attacker to execute arbitrary code.

sudo 1.6.x and 1.7.x before 1.7.9p1, and 1.8.x before 1.8.4p5, does not properly support configurations that use a netmask syntax, which allows local users to bypass intended command restrictions in opportunistic circumstances by executing a command on a host that has an IPv4 address.

Mitigation

Update the affected packages:

i686:
    sudo-debuginfo-1.7.4p5-12.14.amzn1.i686
    sudo-1.7.4p5-12.14.amzn1.i686

src:
    sudo-1.7.4p5-12.14.amzn1.src

x86_64:
    sudo-debuginfo-1.7.4p5-12.14.amzn1.x86_64
    sudo-1.7.4p5-12.14.amzn1.x86_64
