Debian Security Advisory DSA-5505-1 [email protected]

Package : lldpd
CVE ID : CVE-2023-41910

Matteo Memelli reported an out-of-bounds read flaw when parsing CDP
addresses in lldpd, an implementation of the IEEE 802.1ab (LLDP)
protocol. A remote attacker can take advantage of this flaw to cause a
denial of service via a specially crafted CDP PDU packet.

For the oldstable distribution (bullseye), this problem has been fixed
in version 1.0.11-1+deb11u2.

For the stable distribution (bookworm), this problem has been fixed in
version 1.0.16-1+deb12u1.

We recommend that you upgrade your lldpd packages.

For the detailed security status of lldpd please refer to its security
tracker page at:
https://security-tracker.debian.org/tracker/lldpd
