Scientific Linux Security Update : mailx on SL6.x, SL7.x i386/x86_64 (20141216)

high Nessus Plugin ID 80075

Language:

Synopsis

The remote Scientific Linux host is missing one or more security updates.

Description

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 and the direct command execution functionality.
(CVE-2004-2771, CVE-2014-7844)

Note: Applications using mailx to send email to addresses obtained from untrusted sources will still remain vulnerable to other attacks if they accept email addresses which start with '-' (so that they can be confused with mailx options). To counteract this issue, this update also introduces the '--' option, which will treat the remaining command line arguments as email addresses.

Solution

Update the affected mailx and / or mailx-debuginfo packages.
