Debian 1.6-1+deb11u1 Moderate: Libndp Buffer Overflow Risk

A buffer overflow was discovered in libndp, a library implementing the
IPv6 Neighbor Discovery Protocol (NDP), which could result in denial of
service or potentially the execution of arbitrary code if malformed
IPv6 router advertisements are processed.

For the oldstable distribution (bullseye), this problem has been fixed
in version 1.6-1+deb11u1.

For the stable distribution (bookworm), this problem has been fixed in
version 1.8-1+deb12u1.

We recommend that you upgrade your libndp packages.
