Gentoo Linux Security Advisory
Title: ldns: Arbitrary code execution (GLSA 201401-25)
Severity: normal
Exploitable: remote
Date: January 21, 2014
Bug(s): #384249
ID: 201401-25
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: net-libs/ldns
Vulnerable: < 1.6.11
Unaffected: >= 1.6.11
Architectures: All supported architectures
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: Code: | # 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.
