Synopsis

The remote Fedora host is missing one or more security updates.

Description

The remote Fedora 39 host has packages installed that are affected by multiple vulnerabilities as referenced in the FEDORA-2024-ef8a7031e7 advisory.

# Update to BIND 9.18.28

## Security Fixes

- A malicious DNS client that sent many queries over TCP but never read the responses could cause a server to respond slowly or not at all for other clients. This has been fixed. (CVE-2024-0760) [GL #4481]

- It is possible to craft excessively large resource records sets, which have the effect of slowing down database processing. This has been addressed by adding a configurable limit to the number of records that can be stored per name and type in a cache or zone database. The default is 100, which can be tuned with the new max-records-per-type option. [GL #497] [GL #3405]

It is possible to craft excessively large numbers of resource record types for a given owner name, which has the effect of slowing down database processing. This has been addressed by adding a configurable limit to the number of records that can be stored per name and type in a cache or zone database. The default is 100, which can be tuned with the new max-types-per-name option. (CVE-2024-1737) [GL #3403]

ISC would like to thank Toshifumi Sakaguchi who independently discovered and responsibly reported the issue to ISC. [GL #4548]

- Validating DNS messages signed using the SIG(0) protocol (RFC 2931) could cause excessive CPU load, leading to a denial-of-service condition. Support for SIG(0) message validation was removed from this version of named. (CVE-2024-1975) [GL #4480]

- Due to a logic error, lookups that triggered serving stale data and required lookups in local authoritative zone data could have resulted in an assertion failure. This has been fixed. (CVE-2024-4076) [GL #4507]

Potential data races were found in our DoH implementation, related to HTTP/2 session object management and endpoints set object management after reconfiguration. These issues have been fixed. [GL #4473]

ISC would like to thank Dzintars and Ivo from nic.lv for bringing this to our attention.

- When looking up the NS records of parent zones as part of looking up DS records, it was possible for named to trigger an assertion failure if serve-stale was enabled. This has been fixed. [GL #4661]

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
