Azure Linux 3.0 Security Update: c-ares / fluent-bit / nodejs / nodejs18 / python-gevent (CVE-2024-25629)

medium Nessus Plugin ID 215781

Synopsis

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

Description

The version of c-ares / fluent-bit / nodejs / nodejs18 / python-gevent 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-2024-25629 advisory.

 - c-ares is a C library for asynchronous DNS requests. `ares__read_line()` is used to parse local configuration files such as `/etc/resolv.conf`, `/etc/nsswitch.conf`, the `HOSTALIASES` file, and if using a c-ares version prior to 1.27.0, the `/etc/hosts` file. If any of these configuration files has an embedded `NULL` character as the first character in a new line, it can lead to attempting to read memory prior to the start of the given buffer which May result in a crash. This issue is fixed in c-ares 1.27.0.
 No known workarounds exist. (CVE-2024-25629)

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.
