RHSA-2014:1999-01 -- Redhat mailxID: oval:org.secpod.oval:def:501474 | Date: (C)2014-12-19 (M)2023-07-28 |
Class: PATCH | Family: unix |
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. 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 "-" . 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.
