Synopsis

The remote SUSE host is missing a security update.

Description

The remote SUSE Linux SLES12 host has packages installed that are affected by a vulnerability as referenced in the SUSE- SU-2022:0908-1 advisory.

- When using forwarders, bogus NS records supplied by, or via, those forwarders may be cached and used by named if it needs to recurse for any reason, causing it to obtain and pass on potentially incorrect answers. Some examples of configurations that will be vulnerable are: - Resolvers using per zone or global forwarding with forward first (forward first is the default). - Resolvers not using global forwarding, but with per-zone forwarding with either forward first (the default) or forward only.
- Resolvers configured with global forwarding along with zone statements that disable forwarding for part of the DNS namespace. Resolvers using per zone or global forwarding with forward first ( forward first is the default). Resolvers not using global forwarding, but with per-zone forwarding with either forward first (the default) or forward only . Authoritative-only BIND 9 servers are not vulnerable to this flaw.The cache could become poisoned with incorrect records leading to queries being made to the wrong servers, which might also result in false information being returned to clients. (CVE-2021-25220)

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