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.
ldns contains a heap-based buffer overflow in the ldns_rr_new_frm_str_internal function.
A remote attacker could execute arbitrary code or cause a Denial of Service condition with a crafted Resource Record.
There is no known workaround at this time.
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.
OS | Version | Architecture | Package | Version | Filename |
---|---|---|---|---|---|
Gentoo | any | all | net-libs/ldns | < 1.6.11 | UNKNOWN |
