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"
