Summary: Updated mailx packages that fix two security issues are now available for Red Hat Enterprise Linux 6 and 7. Red Hat Product Security has rated this update as having Moderate security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section. 2. Relevant releases/architectures: Red Hat Enterprise Linux Client (v. 7) - x86_64 Red Hat Enterprise Linux ComputeNode (v. 7) - x86_64 Red Hat Enterprise Linux Desktop (v. 6) - i386, x86_64 Red Hat Enterprise Linux HPC Node (v. 6) - x86_64 Red Hat Enterprise Linux Server (v. 6) - i386, ppc64, s390x, x86_64 Red Hat Enterprise Linux Server (v. 7) - ppc64, s390x, x86_64 Red Hat Enterprise Linux Workstation (v. 6) - i386, x86_64 Red Hat Enterprise Linux Workstation (v. 7) - x86_64 3. Description: The mailx packages contain a mail user agent that is used to manage mail using scripts. 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. All mailx users are advised to upgrade to these updated packages, which contain backported patches to correct these issues. 4. Solution: Before applying this update, make sure all previously released errata relevant to your system have been applied. This update is available via the Red Hat Network.
