Synopsis

The remote Gentoo host is missing one or more security-related patches.

Description

The remote host is affected by the vulnerability described in GLSA-201401-25 (ldns: Arbitrary code execution)

 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.

Solution

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.
