Amazon Linux AMI : cups (ALAS-2023-1796)

medium Nessus Plugin ID 179766

Language:

Synopsis

The remote Amazon Linux AMI host is missing a security update.

Description

The version of cups installed on the remote host is prior to 1.4.2-67.23. It is, therefore, affected by a vulnerability as referenced in the ALAS-2023-1796 advisory.

 - OpenPrinting CUPS is an open source printing system. In versions 2.4.2 and prior, a heap buffer overflow vulnerability would allow a remote attacker to launch a denial of service (DoS) attack. A buffer overflow vulnerability in the function `format_log_line` could allow remote attackers to cause a DoS on the affected system. Exploitation of the vulnerability can be triggered when the configuration file `cupsd.conf` sets the value of `loglevel `to `DEBUG`. No known patches or workarounds exist at time of publication. (CVE-2023-32324)

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

Solution

Run 'yum update cups' to update your system.
