Security Bulletin

This security bulletin contains information about 2 vulnerabilities.

1) OS Command Injection

EUVDB-ID: #VU64573

Risk: High

CVSSv3.1: 7.1 [CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2015-20107

CWE-ID: CWE-78 - Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection')

Exploit availability: No

Description

The vulnerability allows a remote attacker to execute arbitrary shell commands on the target system.

The vulnerability exists due to improper input validation in the mailcap module, which does not escape characters into commands discovered in the system mailcap file. A remote unauthenticated attacker can pass specially crafted data to the applications that call mailcap.findmatch with untrusted input and execute arbitrary OS commands on the target system.

Mitigation

Update the affected package python3 to the latest version.
