Fedora 12 : spamass-milter-0.3.1-18.fc12 (2010-5096)
High Nessus Plugin ID 47378
SynopsisThe remote Fedora host is missing a security update.
DescriptionThis update includes a fix for a problem where if the milter is running using the '-x' option to expand aliases before passing inbound mail through SpamAssassin, a malicious client using a carefully-crafted SMTP session could execute arbitrary code on the mail server. The fix avoids the use of a shell in the alias expansion and hence there is no longer a problem with having to sanitize input from the client. This problem has been assigned CVE-2010-1132, which is tracked upstream at https://savannah.nongnu.org/bugs/?29136 The update also contains improved Received-header-generation for message submission and a fix for a problem where the milter would erroneously log warnings about the mail server's configuration when the first message from a non-authenticated client passed through. As part of the fix for this issue, the required milter macro configuration for the mail server has changed slightly: see the README file included in the package for details.
Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
SolutionUpdate the affected spamass-milter package.
