Test ID:1.3.6.1.4.1.25623.1.0.703104
Category:Debian Local Security Checks
Title:Debian: Security Advisory (DSA-3104-1)
Summary:The remote host is missing an update for the Debian 'bsd-mailx' package(s) announced via the DSA-3104-1 advisory.
Description:Summary:
The remote host is missing an update for the Debian 'bsd-mailx' package(s) announced via the DSA-3104-1 advisory.

Vulnerability Insight:
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.

Affected Software/OS:
'bsd-mailx' package(s) on Debian 7.

Solution:
Please install the updated package(s).
