Synopsis
=======
tla includes a vulnerable version of the neon library.

Background
=========
GNU Arch (tla) is a revision control system suited for widely
distributed development.

Affected packages
================
    -------------------------------------------------------------------
     Package       /    Vulnerable    /                     Unaffected
    -------------------------------------------------------------------
  1  dev-util/tla      < 1.2.1_pre1                      >= 1.2.1_pre1

Description
==========
Stefan Esser discovered a vulnerability in the code of the neon library
(GLSA 200405-13): if a malicious date string is passed to the
ne_rfc1036_parse() function, it can trigger a string overflow into
static heap variables. tla includes it's own version of the library.

Impact
=====
When connected to a malicious WebDAV server, this vulnerability could
allow execution of arbitrary code with the rights of the user running
tla.

Workaround
=========
There is no known workaround at this time.

Resolution
=========
All users of tla should upgrade to the latest stable version:

    # emerge sync

    # emerge -pv ">=dev-util/tla-1.2.1_pre1"
    # emerge ">=dev-util/tla-1.2.1_pre1"
