CVE-2015-2775 Mailman vulnerability
Title: Mailman vulnerability
Summary: Mailman could be made to run programs if it processed a specially crafted
list name.
It was discovered that Mailman incorrectly handled special characters
in list names. A local attacker could use this issue to perform a path
traversal attack and execute arbitrary code as the Mailman user.
Instructions: In general, a standard system update will make all the necessary changes.

mailman: directory traversal in MTA transports that deliver programmatically
Directory traversal vulnerability in GNU Mailman before 2.1.20, when not using a static alias, allows remote attackers to execute arbitrary files via a .. (dot dot) in a list name.
It was found that mailman did not sanitize the list name before passing it to certain MTAs. A local attacker could use this flaw to execute arbitrary code as the user running mailman.

CVE-2015-2775 mailman: directory traversal in MTA transports that deliver programmatically
A path traversal vulnerability has been discovered and fixed in Mailman 2.1.20. This vulnerability is only exploitable by a local user on a Mailman server where the suggested Exim transport, the Postfix postfix_to_mailman.py transport or some other programmatic MTA delivery not using aliases is employed.
The patch to Mailman/Utils.py at can be applied with at most a line number offset to any Mailman 2.1.x version, but the referenced mm_cfg.ACCEPTABLE_LISTNAME_CHARACTERS setting didn't exist before Mailman 2.1.11 so if you are patching an older version, you need to add:
ACCEPTABLE_LISTNAME_CHARACTERS = '[-+_.=a-z0-9]'
to mm_cfg.py and/or Defaults.py.
