Azure Linux 3.0 Security Update: c-ares / fluent-bit / grpc / nodejs (CVE-2023-31130)

medium Nessus Plugin ID 234060

Synopsis

The remote Azure Linux host is missing one or more security updates.

Description

The version of c-ares / fluent-bit / grpc / nodejs installed on the remote Azure Linux 3.0 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the CVE-2023-31130 advisory.

- c-ares is an asynchronous resolver library. ares_inet_net_pton() is vulnerable to a buffer underflow for certain ipv6 addresses, in particular 0::00:00:00/2 was found to cause an issue. C-ares only uses this function internally for configuration purposes which would require an administrator to configure such an address via ares_set_sortlist(). However, users May externally use ares_inet_net_pton() for other purposes and thus be vulnerable to more severe issues. This issue has been fixed in 1.19.1. (CVE-2023-31130)

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

Solution

Update the affected packages.
