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"
