{"id":"UBUNTU-CVE-2023-32324","details":"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.","modified":"2026-04-22T14:06:42.768016Z","published":"2023-06-01T11:00:00Z","related":["USN-6128-1","USN-6128-2"],"upstream":["CVE-2023-32324"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2023-32324"},{"type":"REPORT","url":"https://www.openwall.com/lists/oss-security/2023/06/01/1"},{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-6128-1"},{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-6128-2"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2023-32324"}],"affected":[{"package":{"name":"cups","ecosystem":"Ubuntu:Pro:16.04:LTS","purl":"pkg:deb/ubuntu/cups@2.1.3-4ubuntu0.11+esm2?arch=source&distro=esm-infra/xenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.1.3-4ubuntu0.11+esm2"}]}],"versions":["2.1.0-4ubuntu3","2.1.0-5","2.1.0-6","2.1.0-6ubuntu1","2.1.0-7","2.1.2-1","2.1.2-2","2.1.3-1","2.1.3-1build1","2.1.3-3","2.1.3-4","2.1.3-4ubuntu0.2","2.1.3-4ubuntu0.3","2.1.3-4ubuntu0.4","2.1.3-4ubuntu0.5","2.1.3-4ubuntu0.6","2.1.3-4ubuntu0.7","2.1.3-4ubuntu0.8","2.1.3-4ubuntu0.9","2.1.3-4ubuntu0.10","2.1.3-4ubuntu0.11","2.1.3-4ubuntu0.11+esm1"],"ecosystem_specific":{"availability":"Available
