+ <title>getmail: Filesystem overwrite vulnerability</title>
+ <synopsis>
+ getmail contains a vulnerability that could potentially allow any local
+ user to create or overwrite files in any directory on the system. This flaw
+ can be escalated further and possibly lead to a complete system compromise.

+ <description>
+ <p>
+ David Watson discovered a vulnerability in getmail when it is
+ configured to run as root and deliver mail to the maildirs/mbox files
+ of untrusted local users. A malicious local user can then exploit a
+ race condition, or a similar symlink attack, and potentially cause
+ getmail to create or overwrite files in any directory on the system.
+ </p>
+ </description>
+ <impact type="high">
+ <p>
+ An untrusted local user could potentially create or overwrite files in
+ any directory on the system. This vulnerability may also be exploited
+ to have arbitrary commands executed as root.
+ </p>
+ </impact>
+ <workaround>
+ <p>
+ Do not run getmail as a privileged user; or, in version 4, use an
+ external MDA with explicitly configured user and group privileges.
+ </p>
+ </workaround>
+ <resolution>
+ <p>
+ All getmail users should upgrade to the latest version:
+ </p>
+ <code>
+ # emerge sync
+
+ # emerge -pv &quot;&gt;=net-mail/getmail-4.2.0&quot;
+ # emerge &quot;&gt;=net-mail/getmail-4.2.0&quot;</code>
+ </resolution>
