From c4b4a638ba27ca0ac0fdc272b3aa6505a19b6d85 Mon Sep 17 00:00:00 2001 From: "schitrod=cisco.com@lists.openembedded.org" Date: Tue, 13 Jun 2023 04:04:39 -0700 Subject: cups: Fix CVE-2023-32324 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.
