------------------------------------------------------------------------- Debian LTS Advisory DLA-3903-1 [email protected] https://www.debian.org/lts/security/ Daniel Leidert September 29, 2024 https://wiki.debian.org/LTS
-------------------------------------------------------------------------

Package : unbound Version : 1.13.1-1+deb11u3 CVE ID : CVE-2024-43167 CVE-2024-43168 Debian Bug : 1078647

Two vulnerabilities were discovered in unbound, a validating, recursive, caching DNS resolver. Specially crafted input could cause a heap-buffer-overflow leading to memory corruption and potentially causing the application to crash or allowing arbitrary code execution (CVE-2024-43168). A NULL pointer dereference flaw could allow an attacker who can invoke specific sequences of API calls to cause a segmentation fault and a denial of service (CVE-2024-43167).

For Debian 11 bullseye, these problems have been fixed in version 1.13.1-1+deb11u3.

We recommend that you upgrade your unbound packages.
