Synopsis
========
A heap-based buffer overflow in ldns might allow remote attackers to
execute arbitrary code or cause a Denial of Service condition.
Background
==========
ldns is a fast DNS library with the goal to simplify DNS programming
and to allow developers to easily create software conforming to current
RFCs and Internet drafts.
Affected packages
=================
——————————————————————-
Package / Vulnerable / Unaffected
——————————————————————-
1 net-libs/ldns < 1.6.11 >= 1.6.11
Description
===========
ldns contains a heap-based buffer overflow in the
ldns_rr_new_frm_str_internal function.
Impact
======
A remote attacker could execute arbitrary code or cause a Denial of
Service condition with a crafted Resource Record.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All ldns users should upgrade to the latest version:
# emerge –sync
# emerge –ask –oneshot –verbose “>=net-libs/ldns-1.6.11”
Packages which depend on this library may need to be recompiled. Tools
such as revdep-rebuild may assist in identifying these packages.
NOTE: This is a legacy GLSA. Updates for all affected architectures are
available since October 11, 2011. It is likely that your system is
already no longer affected by this issue.
