A flaw was found in the Bind package, where a flaw in ‘named’ can cause a small memory leak in key processing when using TKEY records in Diffie-Hellman mode with OpenSSL 3.0.0 and later versions. This flaw allows an attacker to gradually erode available memory to the point where ‘named’ crashes due to a lack of resources.

This flaw only affects versions BIND-9.18.0 and higher, whereas Red Hat ships BIND-9.16 and lower versions. Therefore, versions of BIND shipped with Red Hat Products are not affected by this flaw.
