Debian LTS Advisory DLA-3578-1 [email protected]
https://www.debian.org/lts/security/ Markus Koschany
September 22, 2023 https://wiki.debian.org/LTS

Package : lldpd
Version : 1.0.3-1+deb10u2
CVE ID : CVE-2023-41910

Matteo Memelli discovered a flaw in lldpd, an implementation of the IEEE
802.1ab protocol. By crafting a CDP PDU packet with specific
CDP_TLV_ADDRESSES TLVs, a malicious actor can remotely force the lldpd
daemon to perform an out-of-bounds read on heap memory.

For Debian 10 buster, this problem has been fixed in version
1.0.3-1+deb10u2.

We recommend that you upgrade your lldpd packages.

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