Package        : libndp
Version        : 1.6-1+deb10u1
CVE ID         : CVE-2024-5564
Debian Bug     : 1072366

It was discovered that there was a buffer overflow vulnerability in
libndp, a library for implementing IPv6's "Neighbor Discovery
Protocol" (NDP) and is used by Network Manager and other networking
tools.

A local, malicious user could have caused a buffer overflow in
Network Manager by sending a malformed IPv6 router advertisement
packet. This issue existed because libndp was not correctly
validating route length information.

For Debian 10 buster, this problem has been fixed in version
1.6-1+deb10u1.

We recommend that you upgrade your libndp packages.

For the detailed security status of libndp please refer to
its security tracker page at:
