**Name of the Vulnerable Software and Affected Versions** PDNS Recursor versions prior to 5.2.6-0+deb13u1 **Description** Insufficient validation of delegation information could lead to cache pollution in PDNS Recursor, a resolving name server. The changes required to address this are too extensive to backport to the version of PDNS Recursor included in the oldstable distribution (bookworm). **Recommendations** Upgrade pdns-recursor packages to version 5.2.6-0+deb13u1 or later. For affected setups using the oldstable distribution (bookworm), upgrade to Debian stable/trixie.
