 - ------------------------------------------------------------------------- Debian LTS Advisory DLA-3498-1 [email protected] https://www.debian.org/lts/security/ Chris Lamb July 18, 2023 https://wiki.debian.org/LTS
 - -------------------------------------------------------------------------

 Package : bind9 Version : 1:9.11.5.P4+dfsg-5.1+deb10u9 CVE ID : CVE-2023-2828

 It was discovered that there was a potential denial of service (DoS) in bind9, the popular Domain Name Server (DNS) server.

 Shoham Danino, Anat Bremler-Barr, Yehuda Afek and Yuval Shavitt discovered that a flaw in the cache-cleaning algorithm used in named can cause that named's configured cache size limit can be significantly exceeded, potentially resulting in a denial of service attack.

 For Debian 10 buster, this problem has been fixed in version 1:9.11.5.P4+dfsg-5.1+deb10u9.

 We recommend that you upgrade your bind9 packages.
