Detail
It was discovered that bsd-mailx, an implementation of the "mail" command, had an undocumented feature which treats syntactically valid email addresses as shell commands to execute. Users who need this feature can re-enable it using the "expandaddr" in an appropriate mailrc file. This update also removes the obsolete -T option. An older security vulnerability, CVE-2004-2771, had already been addressed in the Debian's bsd-mailx package. Note that this security update does not remove all mailx facilities for command execution, though. Scripts which send mail to addresses obtained from an untrusted source (such as a web form) should use the "--" separator before the email addresses (which was fixed to work properly in this update), or they should be changed to invoke "mail -t" or "sendmail -i -t" instead, passing the recipient addresses as part of the mail header. For the stable distribution (wheezy), this problem has been fixed in version 8.1.2-0.20111106cvs-1+deb7u1. We recommend that you upgrade your bsd-mailx packages. |

Title: | RHSA-2014:1999 -- mailx security update (Moderate) | ||
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. | ||
