Amazon Linux 2023 Security Advisory: ALAS-2023-240
Advisory Release Date: 2023-07-05 20:13 Pacific
Advisory Updated Date: 2023-07-20 00:56 Pacific
Severity: Important

Issue Overview:

A vulnerability was found in BIND. The effectiveness of the cache-cleaning algorithm used in named can be severely diminished by querying the resolver for specific RRsets in a certain order, effectively allowing the configured max-cache-size limit to exceed significantly. (CVE-2023-2828)

If the `recursive-clients` quota is reached on a BIND 9 resolver configured with both `stale-answer-enable yes;` and `stale-answer-client-timeout 0;`, a sequence of serve-stale-related lookups could cause `named` to loop and terminate unexpectedly due to a stack overflow.
This issue affects BIND 9 versions 9.16.33 through 9.16.41, 9.18.7 through 9.18.15, 9.16.33-S1 through 9.16.41-S1, and 9.18.11-S1 through 9.18.15-S1. (CVE-2023-2911)
