F5 Networks BIG-IP : Mailx vulnerabilities (K16945)

high Nessus Plugin ID 99238

Language:

Synopsis

The remote device is missing a vendor-supplied security patch.

Description

CVE-2014-7844 The expand function in fio.c in Heirloom mailx 12.5 and earlier and BSD mailx 8.1.2 and earlier allows remote attackers to execute arbitrary commands via shell meta characters in an email address.

CVE-2004-2771 A flaw was found in the way mailx handled the parsing of email addresses. A syntactically valid email address could allow a local attacker to cause mailx to execute arbitrary shell commands through shell meta characters (CVE-2004-2771) and the direct command execution functionality (CVE-2014-7844).

Impact

A local attacker can cause mailx to execute arbitrary shell commands through shell meta-characters. These attacks require a trusted user with shell access to the system in question.

Solution

Upgrade to one of the non-vulnerable versions listed in the F5 Solution K16945.
