EulerOS 2.0 SP8 : c-ares (EulerOS-SA-2024-2020)

medium Nessus Plugin ID 202945

Synopsis

The remote EulerOS host is missing a security update.

Description

According to the versions of the c-ares packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

 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)

Tenable has extracted the preceding description block directly from the EulerOS c-ares security advisory.

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 c-ares packages.
